Abstract
Templates of known forms are stored in computer system. The templates are digitized pixels on which connected component analyses are performed resulting in a first list of components. Five to ten of those components are selected to create an ordered feature list for each form. The computer system then captures an optical image of a form positioned on the top of a stack of forms. The optical image is digitized and stored in the computer (or processor) system as a captured digital image of pixels. A connected component analysis is performed on the captured digital image that results in a second list of image components. Image components on the second list are compared to those on the first list and then each succeeding feature in one of the ordered feature lists. If the comparison is successful, the form is known and other marks on the form may then be processed. If the comparison is unsuccessful, a new feature list is tried.
