Abstract
Embodiments of the present application relate to a form recognition method, a form recognition system, and a computer program product for recognizing forms. A form recognition method is provided. The method includes conducting a straight line detection of a form in a form binary image to acquire a plurality of form boundaries of the form and a plurality of positional relationships between the plurality of form boundaries, extracting a plurality of features from the form using the plurality of form boundaries and the positional relationships between the plurality of form boundaries, establishing a feature vector associated with the form based at least in part on the plurality of features, calculating similarities between the form and respective ones of a plurality of template forms based at least in part on the feature vector of the form, and identifying the form based on the calculated similarities.
