Claim:
1. A method for performing initial image processing of a physical document image, comprising: receiving a raw image file from an imaging station, the raw image file comprising an image of a physical document and at least one control target; reading dimensional data of the raw image file; verifying that the raw image file exceeds a predetermined minimum resolution and aspect ratio; applying a light filter upon verifying that the raw image file exceeds the predetermined minimum resolution and aspect ratio; creating an image copy of the raw image file; placing the image copy on top of the raw image file upon creating the copy of the raw image file; converting the image copy to a bitonal format; verifying that the at least one control target is present in the image copy; measuring control target attributes of the at least one control target, wherein measuring the control target attributes of the at least one control target includes: determining whether the control target attributes are within predetermined specifications; discarding the image copy upon a determination that the control target attributes are within the predetermined specifications; performing a static crop of the raw image file based on the control target attributes by removing the at least one control target from the raw image file to create a cropped image; creating a cropped image copy of the cropped image; placing the cropped image copy on top of the cropped image upon creating the copy of the cropped image; measuring a background color of a background of the cropped image copy, wherein the background is separate from a live document portion of the cropped image copy; selecting all contiguous background color pixels of the background based upon the measured background color; determining whether similar background pixels are to be selected; selecting some or all of the similar background pixels upon a determination to select the similar background pixels; creating a mask based on the selected contiguous background color pixels and the selected similar background pixels; and creating a temporary quality control thumbnail file, a temporary metadata thumbnail file, and a high resolution archive file based at least upon the created mask.
