Abstract: The following generally relates to pre-processing signature data. In some examples, the extracted signature data may be used to train a signature classification model configured to identify a signature type for an input signature. As part of the pre-processing, the techniques disclosed herein relate to extracting the signature data from a corpus of signed documents. For example, techniques disclosed herein may use anchor points to define a boundary box. Additionally, the pre-processing may include aligning the image data of the signatures, for example, by correcting a skew. The extracted and aligned signatures may be used to train the signature classification model.

Abstract: A computer system is provided and is programmed to: (1) receive a document; (2) execute a hash function to generate a hash of the document; (3) compare the hash of the document to the plurality of hashes for the plurality of documents; (4) determine if an exact match exists between the hash of the document and the plurality of hashes for the plurality of documents; (5) if an exact match exists, indicate that the received document is a duplicate; and (6) if no exact match exists, the at least one processor is programmed to: (a) perform similarity analysis on the document to compare the document to the plurality of stored documents; (b) determine a similarity measure for the document based on the comparison; (c) compare the similarity measure for the document to a threshold; and (d) indicate that the received document is a potential duplicate based upon the comparison.
