A system and method for comparing digital images, such as checks images used by banks, includes receiving and processing the images to be compared, including scaling the images to a common resolution, as well as filtering them to remove spot noise, background pels, and other non-information carrying elements. One or more regions of each image are selected for comparison. The selected regions are compared to one another by subtracting the pels of one image from the other's pels. A determination is made of whether the two or more images are duplicates of one another, or depict a substantially identical subject, based on the results of the subtractions. Furthermore, the amount of filtering and scaling may be adjusted to enhance the effects of the system to take advantage of common characteristics that may be known or detected in a particular set of images to be compared.

A system and method for applying an endorsement to an electronic image of a bank check. A system is described that includes: an imaging system for generating an endorsement image representing an action taken relative to processing the bank check; a halftone system for converting the endorsement image into a digitally halftoned endorsement image; and a positioning system for placing the digitally halftoned endorsement image onto the electronic image of the bank check.

A document processing system and method for using image quality to sort documents. The document processing system comprises: a document sorting system that designates a destination pocket for each document based on data gathered from each document; a document imaging system that captures an image of each document; and an image quality analysis system that analyzes each image and causes any document having an unacceptable image to be redirected to an unacceptable destination pocket.
