     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0025]    The present disclosure is now described more fully with reference to the accompanying drawings, in which an example embodiment of the present disclosure is shown. The present disclosure can, however, be embodied in several forms and should not be construed as necessarily being limited to the example embodiment disclosed herein. Rather, this example embodiment is provided so that the present disclosure is thorough and complete, and fully conveys the concepts of the present disclosure to those skilled in the relevant art. In addition, features described with respect to certain example embodiments can be combined in and/or with various other example embodiments. Different aspects and/or elements of example embodiments, as herein disclosed, can be combined in a similar manner. 
         [0026]    The terminology used herein can imply indirect or direct, fully or partially, temporarily or permanently, action or inaction. For example, if an element is referred to as being “on”,“connected” or “coupled” to another element, then the element can be directly on, connected to the other element and/or intervening elements may be present, including indirect and/or direct variants. In contrast, when an element is referred to as being “directly connected” or “directly coupled” to another element, there are no intervening elements present. 
         [0027]    Although the terms first, second, etc. can be used herein to describe different elements, components, layouts, layers and/or sections, these elements, components, layouts, layers and/or sections should not necessarily be limited by such terms. These terms are used to distinguish one element, component, layout, layer or section from another element, component, layouts, layer or section. Thus, a first element, component, layout, layer, or section discussed below could be termed a second element, component, layout, layer, or section without departing from the teachings of the present disclosure. 
         [0028]    The terminology used herein can imply actions, processes or events performed by a actor or identically agent referred to as “user”. 
         [0029]    The terminology used herein is for describing particular example embodiments and is not intended to be necessarily limiting of the present disclosure. As used herein, the singular forms “a,” “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms “comprises,” “includes” and/or “comprising,” “including” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence and/or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. 
         [0030]    Unless otherwise defined, all terms (including technical terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terms, such as those defined in commonly used dictionaries or encyclopedias, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and should not be interpreted in an overly idealized and/or overly formal sense unless expressly so defined herein. 
         [0031]    Furthermore, relative terms such as “below,” “lower,” “above,” and “upper” can be used herein to describe one element&#39;s spatial relationship to another element as illustrated in the accompanying drawings. Such relative terms are intended to encompass different orientations of illustrated technologies in addition to the orientation depicted in the accompanying drawings. For example, if a device in the accompanying drawings were turned over, then the elements described as being on the “lower” side of other elements would then be oriented on “upper” sides of the other elements. Similarly, if the device in one of the figures were turned over, elements described as “below” or “underneath” other elements would then be oriented “above” the other elements. Therefore, the example terms “below” and “lower” can encompass both an orientation of above and below. 
         [0032]    As used herein, the term or is intended to mean an inclusive or rather than an exclusive “or.” That is, unless specified otherwise, or clear from context, “X employs A or B” is intended to mean any of the natural inclusive permutations. That is, if X employs A; X employs B; or X employs both A and B, then “X employs A or B” is satisfied under any of the foregoing instances. 
         [0033]    As used herein, the term “about” and/or “substantially” refers to a 10% (from −10% to +10%) variation from the nominal value/term. Such variation is always included in any given value/term provided herein, whether or not such variation is specifically referred thereto. If any disclosures are incorporated herein by reference and such disclosures conflict in part and/or in whole with the present disclosure, then to the extent of conflict, and/or broader disclosure, and/or broader definition of terms, the present disclosure controls. If such disclosures conflict in part and/or in whole with one another, then to the extent of conflict, the later-dated disclosure controls. 
         [0034]    In one aspect, a system provides the ability for a user to create a scene from a raw image that has been uploaded onto a server that has been processed and joined with other components to make a final digital image that can be placed onto a variety of physical products either by printing or attaching A photograph or visage onto a physical item. For example, A user can use several images of faces and for each of those faces create a cartoon body derived from the algorithmic approach and place those cartoon bodies onto an existing piece of artwork that reflects a specific holiday or occasion. For another example and image processing software can take images generated from the aforementioned scheme and add customize text to personalize specific product for a specific holiday or occasion. 
         [0035]      FIG. 9  shows a flowchart of an example embodiment of a process for the generation of an image according to the present disclosure. A process  900  is used for the image generation and described herein. The process  900  is performed via at least one actor, such as a via a user operating a laptop or computer of  FIG. 8 . The process  900  includes a plurality of blocks  901 - 910 , which are performed consecutively. 
         [0036]    In block  901 , a selection is made with respect to a predefined gender criteria of available digital image files. For example, if a selection is made for a symbol referring to one gender, digital image files of only that gender are available.  FIG. 1A  shows the first possible configuration one may be able to proceed with processing, but selecting a figure in configuration spot  101  represented in block  101 , with a choice for possible options of gender presets represented by  102 . Similarly, a different configuration can be selected in spot  103  with either choice of gender as indicated by the buttons  104 . 
         [0037]    In block  902 , a digital image is transmitted to the computer, by means of a image device or address, on a remote or local computer.  FIG. 2  shows a digital image that has been been displayed via a computer. This image can be derived from a digital file on the remote computer of the user or otherwise obtained from another remote location on the internet and copied for the purposes of analysis on the server performing the analysis. An example of this image would be from a web server that contains either a Joint Photographic Export Group (JPEG) digital image format or a portable network graphic (PNG) digital image format. The location of this can be a social media server, like from internet connected servers hosting digital images . 
         [0038]    Both blocks  202  and  203  represent represent clear digital representations of faces within an image copy located on a server. Block  202  represents the face on the left figure and block  203  represents the face of the right figure in image  201 . A digital representation of image  201  is hosted on the server. 
         [0039]    The image depicted by  201  is shown once the person has selected a digital image and is shown in order to confirm a proper image is selected to be processed using the procedure described herein. The algorithm contains several steps and is modular and can be repeated for the same image  201  for both face  202  and face  203 . The algorithm can be run on one more new images to repeat the process of generating a new figure, or restarting a new figure. 
         [0040]    In block  903 , a selection is made upon a digital image to adjust the size, orientation and filter of said digital image.  FIG. 3B  defines the selection of a digital representation of the head of a body in a digital image, referred to herein as a “cropped head”. Block  202  encompasses the head within a bounded box defined by four coordinates in block  304 , in a pixel representation stored within the server, for the upper-left, lower-left, upper-right and lower-right extents of the box. The box extents can be captured through a user input device such as a trackpad, mouse or mobile device input device as indicated by  802 . The locations of these coordinates are defined by initiating the placement of a coordinate system by means of a cursor on any corner, and maintaining an action to the input device, or “dragging”, to the preferred corner on the opposite side of the preferred box width in order to capture the entire face to be processed through the proceeding steps of the algorithm. If the selection of the coordinate is started again, for example, to capture the extent of the face contained in block  203 , the single coordinates of the containing box will be redrawn to encompass that face in block  203 . 
         [0041]      FIG. 3A  contains a digital image window contained in block  201  that reflects, in real time as the box in block  201  is adjusted to contain a digital image copy of the face in block  202  noted by block  202 . The digital image can be rotated with respect to the center of the square coordinate counter-clockwise a set number of degrees-widths. Example degrees widths include 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, and 10°. 
         [0042]      408  may be selected by a digital input device, such as  802 , and dragged across the length of  409  in to determine the extent level of a function to determine the gradient of the face in order to artistically manipulate the digital photograph. The location of  408  on  409  corresponds to a numerical value that can be used in a mathematical equation to determine strength of features. 
         [0043]    The digital image is processed using a mathematical process to determine the magnitude of the gradient of the image. This is made by converting each pixel value into a linear, one channel image, referred to herein as the “grayscale” image. The amount of thresholding of the gradient directly corresponds to the placement of  408  on  409 , varying from 0, 10, 20, 30, 40, 50, 60, 70, 80, 90 or 100 percent threshold image, containing black and transparent pixels. 
         [0044]    Composing refers to the digital placement of a digital image file with respect to any number of other image files, containing transparent, black and color pixels. For every method of composing, each pixel contains color and information regarding order placement within several other composed digital images. For example, if three images are composed upon one another, the image generated show the lowest ordered pixel if and only if all higher ordered layer pixels are transparent. If a lowest ordered pixel is transparent and a higher ordered pixel is a color or black, the higher ordered pixel is generated. If a all pixels for a location in a layer are transparent, the image generated will preserve that transparency for that pixel location. 
         [0045]    This image is regenerated automatically for each new placement of  408  on  409 , and composed over a digital copy of the original image that has been blurred by means of applying a Gaussian blurring filter. 
         [0046]    The Gaussian blurring filter performs a function on the digital image to reduce noise between pixels and decrease pixel variance in each color channel. Color channels can be either red, blue and green, referred to herein as RGB, or CMYK, cyan, yellow, magenta and key. 
         [0047]    The digital image in  FIG. 3B  will represent the changes reflected in rotation upon each interaction with blocks  302  or  303 , with set degree-widths preserved if the box window in  FIG. 3B  is reset by re-selecting a box. When the selection of the selected image is made, there is a selection made by means of a button or a feature indicating the procession into the proceeded step of the process. The image and orientation in block  301  is stored in digital memory, and referred to herein as “completed raw face” along with the stored degree-width offset and used as inputs of the function for the next feature. 
         [0048]    In block  904 , a selection is made to select additional face accessory digital image files to be placed on the “completed raw face”. 
         [0049]    In block  905 , a selection is made to the location of the additional face accessory digital image files with respect to the “completed raw face”. The image in block  301  is stored as a temporary digital file and displayed in block  202  in  FIG. 4D . The user may select a hairstyle in  FIG. 4C . The color of the digital hair selected can be adjusted by means of a wheel containing pixels of commonly used colors referred to as a color wheel contained in block  404  of  FIG. 4A . The wheel contains a range of colors which will automatically update, once a color is selected, the features in the digital hair image, containing transparent, black and color pixels, in  FIG. 4C . The images can selected by means of a digital input selector, such as a trackpad or other input, such as seen in  802 , to drag the component in block  407  and block  406  onto block  202 , such that block  202  is fixed in space and moveable block  402  can be placed by dragging, and block  401  can be placed by dragging. The final image contains the three components blocks  401 ,  402  and  202  within one digital image set consisted of black, transparent and color pixels. 
         [0050]      FIG. 4B  refers to an optional digital image that contains transparent, black and color pixels that can be placed by dragging unto the face and hair. One the user places or elects not to place the optional figure in block  406 , the completed composition of blocks  401 ,  402  and  202 , containing transparent, black and color pixels, will herein be referred to as the “completed digital face”. 
         [0051]    In block  906  a selection is made to the location of the “completed digital face” with respect to a digital image file representing the visage of a body, herein referred to as the “headless body”.  FIG. 5  refers to the proceeding scene whereby a “completed digital face”, consists of the composition of blocks  401 ,  402  and  202 , is placed, by means of a cursor or other digital input device, such as seen in  802 , onto a digital image of the “headless body”, consisting of transparent, black and color pixels. The “completed digital face” is then placed onto the headless body features in block  501  by dragging the image in free space, where the body is in fixed space. The choice of the body can be selected, within the box encased in block  505 , by selecting a smaller image in block  501  representing the same image with larger dimensions in block  501 . Block  501  may contain pixels with adjustable colors that can be selected by one of two ways, by either selecting a colored pixel from a color wheel represented by block  503  in selection window block  504  or by pre-selected one of several colors in block  502 . 
         [0052]    In block  907  a selection is made for optional coloring of colored pixels on the “headless body”. Upon selection of a color for the body and the placement of the “completed digital face”, the composition the “completed digital face” upon the body generates the “completed digital body”, which is a digital image comprised of transparent, black and color pixels. 
         [0053]    The “completed digital body” generation can be repeated for as many predefined body features are available for a given scene, and the image stored in digital memory along and used as inputs of the function for the next feature. 
         [0054]    In block  908  a “completed digital body” is placed in digital space upon the scene.  FIG. 6  represents the placements of a number of “completed digital bodies” onto a pre-defined graphical scene represented by block  607 . The scene is fixed in space and the placement of a “completed digital body”, as shown with block  601 , occurs after completion and the creation of both the “completed digital face”, all customizations and placements previously performed, and the “completed digital body”, and all customizations and placements previously performed. The process of generating a new customized body can be repeated to be placed within blocks  602 ,  603 ,  604 ,  605 , or  606 , for which there are a total of 1, 2, 3, 4, 5 or 6 possible characters that may be placed into a scene. The limit to the number of bodies to be placed on a scene is determined by a pre-defined, and no more than the pre-defined numbers of bodies may be placed. The completed placement of any number of “completed digital bodies” onto the scene will be composed and that digital image, representing a collection of transparent, black and color pixels, will be herein referred to as “completed digital scene”, and is stored into memory as input for a proceeding customization step 
         [0055]      FIG. 7B  represents the “completed digital scene”, with a “completed digital body” shown in block  601 , within a fixed scene in block  607 . Unused vacant spaces for other “completed digital bodies” are shown in blocks  602 ,  603 ,  604 ,  605  and  606 . 
         [0056]    In block  909  a selection for input generated text rasterized into a digital image is made that is placed, in pixel form, on the “completed digital scene” in a location that is determined by a pre-defined property of the scene. 
         [0057]      FIG. 7A  represents a customization panel shown in block  701  for the generation and editing of text to be added to the scene located at block  709 . Text is entered by means of a keyboard by entering, using a keyboard or keyed input device, such as seen in  803 , words or letters represented by block  702  into box  703 . Font selection is made from a drag down field in block  704 . Font size is made from a drag down field in block  705 . Font color is made from a drag down field in block  706 . 
         [0058]    The process of composing the text found on block  702  onto the scene in block  607  on the location of block  709  can be reset by selecting the action represented by block  707 . The process of removing composed text that had been previously composed using the action of block  49  can be performed by the action of block  708 . 
         [0059]    In block  910  an image is stored into digital memory that comprises the resulting image from the action performed following the image generation of block  909 . The composing of text onto a “completed digital scene” generates an image file herein referred to as the “completed digital product”, which is a collection of transparent, black and color pixels stored into digital memory. 
         [0060]      FIG. 8  shows a desktop computer exemplifying the process of the present disclosure, where  801  represents a CPU and monitor, but can be expanded to include a server located at a remote location,  802  represents an input device such as a mouse or, in the case of a laptop computer, an incorporated trackpad device, and  803  represents a keyed input device or keyboard. The preferred embodiment may be a laptop or a remote server, such as viewed through a VNC protocol.
