Signature mark detection
Abstract:
A system and method for detection of signature marks in documents are provided. The method includes selecting candidate text objects in document pages and identifying a sequence of elements therein. The sequence has a numbering pattern including an incremental part and optionally a fixed part. Missing elements between two detected elements of the sequence are permitted. For an identified sequence, a model of the sequence is generated, which includes 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. The sequence is then validated with the model, allowing elements of the sequence in the pages of the document to be identified as signature marks.
