Systems and methods for classifying payment documents during mobile image processing
First Claim
1. A payment document classification system, comprising:
- a communication unit which receives an image of a payment document captured by a mobile device;
a preprocessing unit which extracts at least one feature from the image;
a comparison unit which compares the at least one extracted feature with at least one known feature of a payment document type to determine a likelihood that the payment document matches the at least one payment document type, wherein the comparison unit is further configured to compare a plurality of extracted features with a plurality of known features in a series, starting with an extracted feature which requires the least computation time of the plurality of extracted features; and
a classification unit which classified the payment document as at least one payment document type based on the likelihood that the payment document matches the at least one payment document type.

Abstract
Systems and methods are provided for processing an image of a financial payment document captured using a mobile device and classifying the type of payment document in order to extract the content therein. These methods may be implemented on a mobile device or a central server, and can be used to identify content on the payment document and determine whether the payment document is ready to be processed by a business or financial institution. The system can identify the type of payment document by identifying features on the payment document and performing a series of steps to determine probabilities that the payment document belongs to a specific document type. The identification steps are arranged starting with the fastest step in order to attempt to quickly determine the payment document type without requiring lengthy, extensive analysis.

9. A method of classifying a payment document, comprising:
-
receiving an image of a payment document captured by a mobile device; extracting at least one feature from the image; comparing the at least one extracted feature with at least one known feature of a payment document type to determine a likelihood that the payment document matches the at least one payment document type, wherein comparing further includes comparing a plurality of extracted features with a plurality of known features in a series, starting with an extracted feature which requires the least computation time of the plurality of extracted features; and classifying the payment document as at least one payment document type based on the likelihood that the payment document matches the at least one payment document type. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 19)

17. A payment document classification system, comprising:
-
a communication unit which receives an image of a payment document captured by a mobile device; a preprocessing unit which extracts a plurality of features from the image; a comparison unit which compares the plurality of extracted features with a plurality of known features of a payment document type in a series until one of the plurality of extracted features matches one of the plurality of known features, wherein the comparison starts with an extracted feature which requires the least computation time of the plurality of extracted features; and a classification unit which classified the payment document as at least one payment document type when at least one extracted feature matches at least one known feature.
