     DETAILED DESCRIPTION 
     According to the various embodiments of the present disclosure, systems and methods are provided for digitized document image data spillage recovery. In some examples, documents printed on preprinted forms spill outside of the bounding boxes identifying where the data should be. Contours around the preprinted bounding boxes may truncate data spillage outside of the preprinted boxes, resulting in data loss during optical character recognition (OCR) processing. As described herein, systems and methods ensure that data spillage outside of preprinted boxes and identifying contours is included in the contour by resizing it to only include spillage and not data that could be included by resizing the contour. In some examples, data spillage recovers how much data spills over into adjacent boxes. 
     Exemplary embodiments of digitized document image data spillage recovery include and are not limited to one or more sections, portions or regions, such as an earnings section or deduction section of a paystub, or different preprinted boxes on IRS tax forms. Other examples may comprise government forms, business forms, or any document, form, image, paper, or other publication used for any purpose. 
       FIG. 1  illustrates a system  100  configured to provide digitized document image data spillage recovery according to an example of the present disclosure. As further discussed below, system  100  may include client device  105 , network  115 , server  120 , and database  125 . Although  FIG. 1  illustrates single instances of the components, system  100  may include any number of components, including one or more processors. 
     As shown in  FIG. 1 , client device  105 , or end node  105 , may be a network-enabled computer. As referred to herein, a network-enabled computer may include, but is not limited to: e.g., a computer device, or communications device including, e.g., a server, a network appliance, a personal computer, a workstation, a mobile device, a phone, a handheld PC, a personal digital assistant, a thin client, a fat client, an Internet browser, or other device. Client device  105  also may be a mobile device; for example, a mobile device may be a smart phone, a laptop computer, a tablet computer, a wearable device, and/or any other like mobile device or portable computing device. 
     In various examples according to the present disclosure, client device  105  of system  100  may execute one or more applications  110 , such as software applications, that enable, for example, network communications with one or more components of system  100  and transmit and/or receive data. In some examples, an application  110  may be installed on client device  105 , such as a mobile device. Application  110  may include instructions to perform digitized document image data spillage recovery as described herein. In some examples, application  110  may include instructions to determine whether or not to perform a portion of digitized document image data spillage recovery on client device  105  and/or transmit, via one or more networks  115 , the digitized document image to another system, such as a remote database, server, or third party system. Client device  105  may be in communication with one or more servers  120  via one or more networks  115 , and may operate as a respective front-end to back-end pair with server  120 . Client device  105  may transmit, for example from a mobile device application  110  executing on client device  105 , one or more requests to server  120 . The one or more requests may be associated with retrieving data from server  120 . Server  120  may receive the one or more requests from client device  105 . Based on the one or more requests from client device  105 , server  120  may be configured to retrieve the requested data from one or more databases  125 . Based on receipt of the requested data from one or more databases  125 , server  120  may be configured to transmit the received data to client device  105 , the received data being responsive to one or more requests. 
     Data associated with the digitized document image may be received, captured, or otherwise obtained through a variety of processes. In some examples, a digitized document image may be received from one or more computing devices, including but not limited to, scanners, sensors, cameras, mobile devices, and the like and/or any combination thereof. In some examples, the image may comprise a .gif, .bmp, .tiff, .png, .jpeg file format or the like. In some examples, the digitized document image may be received from local storage. In some examples, digitized document image may be received from a cloud. For example, cloud computing may comprise an Internet connection between the systems that are operating in the cloud. The cloud may comprise a plurality of systems such that one or more shared resources, such as processing, peripherals, software, data, servers, and the like are provided to any system of the cloud so as to allow access and distribution of services and/or data between the systems of the cloud. 
     Server  120  may include one or more processors, which are coupled to memory. Server  120  may be configured as a central system, server or platform to control and call various data at different times to execute a plurality of workflow actions. Server  120  may be configured to connect to database  125 . Server  120  may be connected to at least one client device  105 . 
     Network  115  may be one or more of a wireless network, a wired network or any combination of wireless network and wired network, and may be configured to connect client device  105  to server  120 . For example, network  115  may include one or more of a fiber optics network, a passive optical network, a cable network, an Internet network, a satellite network, a wireless LAN, a Global System for Mobile Communication (GSM), a Personal Communication Service (PCS), a Personal Area Network (PAN), Wireless Application Protocol (WAP), Multimedia Messaging Service (MMS), Enhanced Messaging Service (EMS), Short Message Service (SMS), Time Division Multiplexing (TDM) based systems, Code Division Multiple Access (CDMA) based systems, D-AMPS, Wi-Fi, Fixed Wireless Data, IEEE 802.11b, 802.15.1, 802.11n and 802.11g, Bluetooth network, or any other wired or wireless network for transmitting and receiving a data signal. 
     In addition, network  115  may include, without limitation, telephone lines, fiber optics, IEEE Ethernet 802.3, a wireless network, a wide area network (WAN), a wireless personal area network (WPAN), a local area network (LAN), a body area network (BAN), a global network such as the Internet, a cellular network, or any combination thereof. Network  115  may utilize one or more protocols of one or more network elements to which they are communicatively coupled. Network  115  may translate to or from other protocols to one or more protocols of network devices. Although network  115  is depicted as a single network, it should be appreciated that according to one or more examples, network  115  may comprise a plurality of interconnected networks, such as, for example, the Internet, a service provider&#39;s network, a cable television network, corporate networks, such as credit card association networks, and home networks. 
     In various examples, network  115  may be configured to provide data communication between a client device  105  and server  120  and between the client devices  105 . For example, data may be communicated between client devices  105  and server  120  through the Internet or other network, and data may be communicated directly between client devices  105  and/or one or more databases  125  without passing through server  120 . Accordingly, network  115  may be one or more of the Internet, Near Field Communication (NFC), Radio Frequency Identification (RFID), Bluetooth, Wi-Fi, and/or the like. Client devices  105  may be same or different devices. 
     System  100  may be configured to process the digitized document image if it is received in a skewed manner. For example, system  100  may be configured to process skew adjustment or morphage of the digitized document image for data spillage recovery. In some examples, skew adjustment or morphage may comprise adjusting or orienting the image such that the image is transformed and aligned to account for skew. For example, the image may be provided at an angle and thus skew correction is utilized to accurately adjust the image. System  100  may be configured to subject the digitized document image for preprocessing for contouring through one or more filters. For example, the image may be preprocessed by an Otsu threshold filter, a despeckle filter, and/or a grayscale filter. In some examples, the Otsu threshold filter may be configured to adjust one or more of brightness and contrast to improve readability of the digitized document image. In some examples, the despeckle filter may be configured to remove speckles, such as noise, from the digitized document image such that one or more pixels are whited out so it no longer remains a part of the image. 
     In some examples, system  100  may be configured to process skew adjustment or morphage of the image, which may comprise processing edge detection to the digitized document image so as to determine linearity of the content of the document based on vertical and horizontal edges. For example, if the edges are not parallel or perpendicular to the edges of the image boundary, system  100  may be configured to determine how many degrees the content should be rotated so as to sufficiently align the parallel or perpendicular edges to the image boundary edges. In the case where an image is tilted at an angle at the time of capture, a four point affine transformation algorithm may be applied by system  100  to correct it. 
     System  100  may be configured to preprocess the digitized document image through at least a first pass to generate a first contour. In some examples, the first pass by system  100  may be configured for contouring one or more portions, such as one or more preprinted boxes. The first pass may include canny edge detection to identify one or more shapes in the image. Image contouring may comprise creating one or more geometric point arrays around the canny edge detection shapes. The geometric point arrays may be collected to create one or more bounding boxes. For example, canny edge detection may return one or more coordinate pairs, such as one or more (x,y) coordinate points. By receiving one or more (x,y) coordinate points, a vector may be created so as to generate one or more bounding boxes. In some examples, the one or more portions may comprise of rectangular-shaped preprinted boxes. The one or more portions may comprise oval regions, circular regions, square regions, polynomial regions, and checked box regions. In some examples, if the one or more portions are not rectangular-shaped, system  100  may be configured to convert the one or more portions to rectangular-shaped dimensions so as to continue processing of the digitized document image. 
     The terms “smudge” or “smudged,” as used herein, refer to any blurring, blocking, bolding, fattening, thickening, or combining of text into an interconnected or indistinct form. The term “blob” as used herein refers to an indeterminate shape, including without limitation a smudged image of one or more characters. The term “spillage” as used herein, refers to any character, text, image, or portion thereof that extends beyond a specified area, field, or range. In some examples, “bounding box” may be interchangeably used with “bounding region.” 
     System  100  may be configured to remove a preprinted bounding region of the first contour to retain text. In some examples, one or more filters, such as line removal digital image filters, may be configured to remove a preprinted bounding region so only text is retained. The line removal digital image filters may be configured to remove horizontal and vertical lines. Accordingly, this process eliminates the preprinted bounding region of a clip of the image. 
     System  100  may use one or more filters, such as dilation and erosion digital image filters, which may be configured to smudge the text (after removal of the lines) into one or more large blobs of pixels. In some examples, the dilation filter may be configured to enlarge objects, and brighten a given region of text within an image by, for example adding pixels, (so white pixels become more white) and the erosion filter may be configured to shrink objects, and make the region of text in white smaller, for example removing pixels, (so remove white pixels where there are already white pixels, such that shapes get thinner, edges may be trimmed). For example, the dilation filter may only be used to smudge the text together into one or more pixel blobs. This also connects pixels of text that straddles lines that were previously removed and pixels composing the straddling text. In some examples, closing may be performed such that dilation filtering precedes erosion filtering. For example, erosion may comprise a post-process data spillage operation that may be configured to remove one or more undesirable artifacts, for example, one or more remaining line segments that “strike out” straddling text. 
     System  100  may be configured to identify the one or more blobs of pixels that straddle, spill, extend, fall out or otherwise exceed a boundary line of preprinted bounding region of the first contour. In some examples, contouring is performed on the blob of pixels so as to identify complete areas of text. This may be used to help locate text for data spillage that is desired for retaining. The resulting contour around the smudged text may be used to encapsulate the pixels composing the text. In some examples, the one or more straddled pixel blobs are based on one or more coordinates associated with a threshold. For example, text may spill over one or more segments of a bounding box, thereby straddling it. The one or more segments may comprise top, bottom, right, and left line segments of the bounding box. Using the bottom left coordinates and bottom right coordinates of a bottom line of the bounding box the text straddles where the x coordinate may represent horizontal in a positive direction from left to right, and the y coordinate may represent vertical in a positive direction from top to bottom. The y value of the topmost pixels comprising the straddling text is less than (above) the y value of the bottom line the text straddles, and correspondingly, the y value of the bottommost pixels comprising the straddling text is greater than (below) the y value of the bottom line the text straddles. Accordingly, this relationship may qualify the text as a data spillage. 
     In one example, system  100  may be configured to process a first function for straddling text with reference to a bottom line of the bounding box, where Y t  may represent the y value of the topmost pixels of straddling text, Y b  may represent the y value of the bottommost pixels of straddling text, and Y 1  may represent the y value of the bottom line: 
       Straddling text(true/false)=( Y   t   &lt;Y   1  &amp;&amp;  Y   1   &lt;Y   b )
 
     Similarly, system  100  may be configured to process the first function for top, left, and right line segments comprising the bounding box contour with the line in between the corresponding pixel end points (e.g. top, left and right) of the text. In some examples, a second function, which may be similar to the first function, may be processed by system  100  directed to text that touches one or more line segments but does not straddle it. 
     System  100  may be configured to resize the first contour to enclose spillage of the one or more blobs of pixels. In some examples, coordinates of the original contour may be compared for determining a sufficient resize. For example, as long one edge, such as a left edge of smudge, is less than a left edge of preprinted bounding region, this may determine whether it is a candidate for data spillage. Straddling may thus be indicated by a top portion of the blob as being above the line, and a bottom portion of the blob as being below the line. 
     System  100  may be configured to overlay the text from the image within the resized contour. In some examples, a logical AND is applied between to determine which data belongs with the new contour, and which does not. For example, coordinates of smudges, such as a y coordinate of the lowest portion of the text within the preprinted bounding region may be adjusted for a new contour to be created. The resized contour may be based on the outermost pixels of text spillage and a new clip may be produced by copying pixels within the resized contour to a new image that comprises the size of the contour. In effect, the original contour is discarded. 
     System  100  may be configured to apply pixel masking to the resized contour. In some examples, a pixel mask is created in relation to the original contour with the smudged contours. Accordingly, pixel masking results in removal of one or more white pixels. Application of the pixel mask allows determination of which data belongs with the new contour and which does not. In one example, one or more white pixels may be removed, and all black pixels that match will remain black. For example, one or more white pixels in the pixel mask may represent data that does not belong with the new contour. 
     System  100  may be configured to process removal of one or more artifacts via ligature processing. In some examples, one or more artifacts may include one or more of lines, marks, holes, spaces or dashes or other like representations appearing in the image. For example, a resulting contour, after applying pixel masking, may illustrate encapsulated data spillage. Artifact, such as line artifact, may be removed by ligature processing. Ligature processing may be used by downstream processing scans to check for one or more word sized contours created based on one or more bounding boxes about the size of printed text height and the approximate width of two or more characters. The word sized contour may be scanned from one direction to another, such as from left to right, identifying one or more pinch points between connected characters, in which case the one or more pinch points may be whited out to produce a separation of characters. Thus, system  100  may be configured to perform one or more conditional checks of the resized contour. In some examples, the one or more conditional checks of the resized contour may be performed via a machine learning model. 
       FIG. 2  illustrates a method  200  for providing digitized document image data spillage recovery according to an example of the present disclosure. As explained below, method  200  may reference same or similar components of system  100 . For example, as described herein, client device may be similar to client device  105  as described above with respect to  FIG. 1 . Exemplary embodiments of digitized document image data spillage recovery include and are not limited to one or more sections, portions or regions, such as an earnings section or deduction section of a paystub, or different preprinted boxes on IRS tax forms. Other examples may comprise government forms, business forms, or any document, form, image, paper, or other publication used for any purpose. 
     At block  205 , an image may be received by one or more processors (similar to one or more processors as described above with respect to  FIG. 1 ). In some examples, the image may comprise a digitized document image. In some examples, data associated with the image may be received, captured, or otherwise obtained through a variety of processes. In some examples, the image may be received from one or more computing devices, including but not limited to, scanners, sensors, cameras, mobile devices, and the like and/or any combination thereof. In some examples, the image may comprise a .gif, .bmp, .tiff, .png, .jpeg file format or the like. In some examples, the image may be received from local storage. In some examples, the image may be received from a cloud. For example, cloud computing may comprise an Internet connection between the systems that are operating in the cloud. The cloud may comprise a plurality of systems such that one or more shared resources, such as processing, peripherals, software, data, servers, and the like are provided to any system of the cloud so as to allow access and distribution of services and/or data between the systems of the cloud. In some examples, processing, by the one or more processors, skew adjustment or morphage of the digitized document image for data spillage recovery may be optionally performed. In some examples, skew adjustment or morphage may comprise adjusting or orienting the image such that the image is transformed and aligned to account for skew. For example, the image may be provided at an angle and thus skew correction is utilized to accurately adjust the image. For example, skew adjustment or morphage of the digitized document image may comprise utilizing, by the one or more processors, edge detection to the digitized document image so as to determine linearity of the content of the document based on vertical and horizontal edges. For example, if the edges are not parallel or perpendicular to the edge of the image boundary, one or more processors may be configured to determine how many degrees the content should be rotated so as to sufficiently align the parallel or perpendicular edges to the edges of the image boundary. Where an image is tilted at an angle at the time of capture, one or more processors may be configured to correct it via one or more algorithms, such as a four point affine transformation algorithm. 
     At block  210 , the image may be processed, by the one or more processors, through at least a first to generate a first contour. In some examples, preprocessing of the image may include application of one or more filters. For example, the image may be preprocessed by an Otsu threshold filter, a despeckle filter, and/or a grayscale filter. In some examples, the Otsu threshold filter may be configured to adjust one or more of brightness and contrast to improve readability of the digitized document image. In some examples, the despeckle filter may be configured to remove speckles, such as noise, from the digitized document image such that one or more pixels are whited out so it no longer remains a part of the image. Further details of the first pass is described in  FIG. 3 . As explained below with reference to  FIG. 3 , it is understood that preprinted boxes must be identified prior to identifying text that straddles them. 
     At block  215 , text may be preserved, by the one or more processors, by removing a preprinted bounding box of the first contour. For example, lines of the preprinted bounding box may be removed such that only text of the clip is preserved. In some examples, the line removal digital image filters are configured to remove horizontal and vertical lines. Accordingly, this process eliminates the preprinted bounding box. 
     At block  220 , one or more filters may be applied, by the one or more processors, to smudge the text so as to generate one or more pixel blobs. For example, filters, such as dilation and erosion digital image filters, are applied to the clip and configured to smudge the text (after the lines have been removed and only the text remains) into one or more large blobs of pixels. In some examples, the dilation filter may be configured to enlarge objects, and brighten a given region of text within an image by, for example adding pixels, (so white pixels become more white) and the erosion filter may be configured to shrink objects, and make the region of text in white smaller, for example removing pixels, (so remove white pixels where there are already white pixels, such that shapes get thinner, edges may be trimmed). For example, the dilation filter may only be used to smudge the text together into one or more blobs of pixels. This also connects pixels of text that straddles lines that were previously removed and pixels composing the straddling text. In some examples, closing may be performed such that dilation filtering precedes erosion filtering. For example, erosion may comprise a post-process data spillage operation that may be configured to remove one or more undesirable artifacts, for example, one or more remaining line segments that “strike out” straddling text. For example, a black blob may indicate where the text originally was located. 
     At block  225 , the one or more pixel blobs may be evaluated, by the one or more processors, that straddle one or more boundaries of the contour. 
     At block  230 , the first contour may be resized, by the one or more processors, so as to enclose spillage of the one or more pixel blobs. Contouring is performed on the blob of pixels so as to identify complete areas of text. This may be used to help locate text for data spillage that is desired for retaining. The resulting contours around the smudged text may be used to encapsulate the pixels composing the text. In some examples, the one or more straddled pixel blobs are based on one or more coordinates associated with a threshold. For example, text may spill over one or more segments of a bounding box, thereby straddling it. The one or more segments may comprise top, bottom, right, and left line segments of the bounding box. Using the bottom left coordinates and bottom right coordinates of a bottom line of the bounding box the text straddles where the x coordinate may represent horizontal in a positive direction from left to right, and the y coordinate may represent vertical in a positive direction from top to bottom. The y value of the topmost pixels comprising the straddling text is less than (above) the y value of the bottom line the text straddles, and correspondingly, the y value of the bottommost pixels comprising the straddling text is greater than (below) the y value of the bottom line the text straddles. Accordingly, this relationship may qualify the text as a data spillage. 
     In one example, the one or more processors may be configured to process a first function for straddling text with reference to a bottom line of the bounding box, Y t  may represent the y value of the topmost pixels of straddling text, Y b  may represent the y value of the bottommost pixels of straddling text, and Y 1  may represent the y value of the bottom line: 
       Straddling text(true/false)=( Y   t   &lt;Y   1  &amp;&amp;  Y   1   &lt;Y   b )
 
     Similarly, the one or more processors may be configured to process the first function for top, left, and right line segments comprising the bounding box contour with the line in between the corresponding pixel end points (e.g. top, left and right) of the text. In some examples, a second function, which may be similar to the first function, may be processed by the one or more processors directed to text that touches one or more line segments but does not straddle it. 
     At block  235 , the text from the image may be overlayed, by the one or more processors, within the resized contour. For example, an outline, such as a thin black outline around text may represent one of the resulting contours from text smudging overlayed on the clip. Other contours, represented by think black outlines, may also qualify for data spillage. For example, once the text has been smudged together into blobs of pixels, canny edge detection may result in an outline that represents location of the smudged text. 
     At block  240 , a mask may be created, by the one or more processors, to remove data resulting from resizing the first contour. For example, the mask may comprise a pixel mask which results in removal of one or more white pixels. 
     At block  245 , the mask may be applied, by the one or more processors, to the resized contour. Application of the pixel mask allows determination of which data belongs with the new contour and which does not. In one example, one or more white pixels may be removed, and all black pixels that match will remain black. For example, one or more white pixels in the pixel mask may represent data that does not belong with the new contour. 
     In some examples, method  200  may comprise artifact removal which may be conducted, by the one or more processors, via ligature processing, including removing line artifacts appearing through the text. In some examples, one or more artifacts may include one or more of lines, marks, holes, spaces or dashes or other like representations appearing in the image. For example, a resulting contour, after applying pixel masking, may illustrate encapsulated data spillage. Artifact, such as line artifact, may be removed by ligature processing. Ligature processing may be used by downstream processing scans to check for one or more word sized contours created based on one or more bounding boxes about the size of printed text height and the approximate width of two or more characters. The word sized contour may be scanned from one direction to another, such as from left to right, identifying one or more pinch points between connected characters, in which case the one or more pinch points may be whited out to produce a separation of characters. 
     At block  250 , thus, one or more conditional checks of resized contour may be performed by the one or more processors. In some examples, the one or more conditional checks of the resized contour may be performed via a machine learning model. 
       FIG. 3  illustrates a method  300  of a first pass for contouring preprinted boxes. As explained below, method  300  may reference same or similar components of system  100 . For example, as described herein, one or more processors may be similar to the one or more processors as described above with respect to  FIG. 1 . 
     In some examples, the first pass by the one or more processors may be configured for contouring one or more portions, such as one or more preprinted boxes. The first pass may include canny edge detection  310  to identify one or more shapes in the image. Image contouring may comprise creating one or more geometric point arrays  315  around the canny edge detection shapes. The geometric point arrays may be collected to create one or more bounding boxes  320 . For example, canny edge detection may return one or more coordinate pairs, such as one or more (x,y) coordinate points. By receiving one or more (x,y) coordinate points, a vector may be created so as to generate one or more bounding boxes. In some examples, the one or more portions may comprise of rectangular-shaped preprinted boxes. The one or more portions may comprise oval regions, circular regions, square regions, polynomial regions, and checked box regions. In some examples, if the one or more portions are not rectangular-shaped, the one or more processors may be configured to convert the one or more portions to rectangular-shaped dimensions so as to continue processing of the digitized document image. Thus, the first pass is configured for contouring one or more preprinted boxes  325 . 
       FIGS. 4A-4H  depict diagrams illustrating digitized document image data spillage recovery according to an example embodiment. As explained below,  FIGS. 4A-4H  may reference same or similar components of system  100 . For example, as described herein, one or more processors may be similar to the one or more processors as described above with respect to  FIG. 1 . Exemplary embodiments of digitized document image data spillage recovery include and are not limited to one or more sections, portions or regions, such as an earnings section or deduction section of a paystub, or different preprinted boxes on IRS tax forms. Other examples may comprise government forms, business forms, or any document, form, image, paper, or other publication used for any purpose. 
     As shown in  FIG. 4A , a portion or clip  400  of a received or captured digitized document image illustrates a data spillage problem. As observed in  FIG. 4A , “JESSICA SARAH JONES”  405  straddles preprinted bounding box  410  since portions of this text  405  spill, extend, fall out or otherwise exceed a boundary line of preprinted bounding box  410 . For example, text  405  may spill over one or more segments of bounding box  410 , thereby straddling it. The one or more segments may comprise top  402 , bottom  402 , right  406 , and left  408  line segments of bounding box  410 . Using the bottom left coordinates and bottom right coordinates of a bottom line of the bounding box  410  the text  405  straddles where the x coordinate may represent horizontal in a positive direction from left to right, and the y coordinate may represent vertical in a positive direction from top to bottom. The y value of the topmost pixels comprising the straddling text  405  is less than (above) the y value of the bottom line  404  the text straddles  405 , and correspondingly, the y value of the bottommost pixels comprising the straddling text  405  is greater than (below) the y value of the bottom line  404  the text straddles  405 . Accordingly, this relationship may qualify the text  405  as a data spillage. 
     In one example, one or more processors may be configured to process a first function for straddling text with reference to a bottom line  404  of the bounding box  410 , where Y t  may represent the y value of the topmost pixels  401  of straddling text  405 , Y b  may represent the y value of the bottommost pixels  403  of straddling text  405 , and Y 1  may represent the y value of the bottom line  404 . 
       Straddling text(true/false)=( Y   t   &lt;Y   1  &amp;&amp;  Y   1   &lt;Y   b )
 
     Similarly, one or more processors may be configured to process the first function for top  402 , right  406 , and left  408  line segments comprising the bounding box contour with the line in between the corresponding pixel end points (e.g. top  402 , right  406 , and left  408 ) of the text. In some examples, a second function, which may be similar to the first function, may be processed by one or more processors directed to text that touches one or more line segments but does not straddle it. 
     As shown in  FIG. 4B , one or more filters, such as line removal digital image filters, are configured to remove the preprinted boxes so only text remains on clip  400 . For example, as observed in  FIG. 4B  in comparison with  FIG. 4A , lines from clip  400  have been removed such that only text of clip  400  is retained. In some examples, the line removal digital image filters are configured to remove horizontal and vertical lines. In this example, removal of the lines incurs white space  415  appearing through “JESSICA SARAH JONES,” which is accounted and explained in further detail with respect to  FIG. 4G . Accordingly, this process eliminates the preprinted bounding box  410  previously shown in  FIG. 4A . 
     As shown in  FIG. 4C , filters, such as dilation and erosion digital image filters, are applied to clip  400  and configured to smudge the text (as illustrated in  FIG. 4B  where the lines have been removed and only the text remains) into one or more large blobs of pixels  420 . For example, a black blob  420  may indicate where the text originally was located. 
     As shown in  FIG. 4D , contouring is performed on the blob of pixels  420  so as to identify complete areas of text. This may be used to help locate text for data spillage that is desired for retaining. The resulting contours  425  around the smudged text may be used to encapsulate the pixels composing the text. 
     As shown in  FIG. 4E , the original contour is represented by the bolder black lines. The thin black outline  430  around the text “TRANSFEREE&#39;S NAME (TYPED) JONES SARAH” represents one of the resulting contours from text smudging overlayed on clip  400 . As observed in  FIG. 4E , other contours  435 ,  440  that may qualify for data spillage include “BOBBY D JESSICA” and “JR OR JONES.” For example, once the text has been smudged together into blobs of pixels  420  (as illustrated in  FIG. 4C ), canny edge detection may result in an outline that represents location of the smudged text. 
     As shown in  FIG. 4F , a pixel mask is created in relation to the original contour with the smudged contours previously depicted in  FIG. 4E . Accordingly, clip  400  illustrates that the pixel mask results in removal of one or more white pixels. Application of the pixel mask allows determination of which data belongs with the new contour and which does not. In one example, “CITY” “ST.” and “ZIP CODE”  445  are white pixels that are removed, and all black pixels that match will stay black. 
     As shown in  FIG. 4G , clip  400  illustrates the resulting contour, post pixel masking applied in  FIG. 4F , encapsulating data spillage. Artifact, such as line artifact  450 , that appears through “JESSICA SARAH JONES” may be removed by ligature processing. For example, in  FIG. 4G , line  450  may be removed after ligature processing and illustrates the contents of the resized contour after data spillage and masking have been applied. 
     As shown in  FIG. 4H , clip  400  illustrates a comparison  455  of the original contour without application of the processes described herein.
