Application ID: 13288109

Base Claim:
1. A method for detection of signature marks in a document, comprising: selecting candidate text objects for each of an ordered set of optical character recognition (OCR) processed document pages; providing for identifying sequences of elements in the candidate text objects, each detected element of an identified sequence occurring on a different page of the document, the sequence having a numbering pattern including an incremental part and optionally a fixed part, missing elements between two detected elements of the sequence being permitted; for an identified sequence: generating a model of the sequence, the model including: the numbering pattern of the sequence, an increment, which is computed based on the distance between pages on which consecutive elements of the sequence are identified, a valid sequence having an increment of greater than 1, and a first page, which corresponds to a page of the document on which the sequence starts; validating the sequence with the model; and for a valid sequence, identifying elements of the sequence in the pages of the document as signature marks.
