Abstract
The pixel count value in each cell of an array of cells located on a set master forms. Each completed form is scanned into a data processing system and the scanned image is compressed and buffered. In accordance with the invention, when the compressed, completed form is ready to be analyzed, only its top part needs to be decompressed. A form signature set is prepared for the decompressed part of the completed form in the same manner as the master signature set was prepared. The first N rows of the form need to be decompressed and a form signature set created from a pixel count value on each cell of an array of cells located in the decompressed portion of the completed form. The form signature set is compared to the master signature set to determine the best match.
