Systems and methods for classifying payment documents during mobile image processing
First Claim
1. A payment document classification system, comprising:
- a communication unit to receive an image of a payment document captured by a camera of a mobile device;
a feature knowledge database to store a set of features, wherein a given feature in the set of stored features is associated with one or more probability values, and each of the one or more probability values represents a probability of occurrence of the given feature in a given payment document type within a set of known payment document types;
a preprocessing unit to extract a set of features from the image;
a classification unit which is configured to;
compare, by one or more processors, the set of extracted features against the set of stored features in the feature knowledge database;
in response to a match between an extracted feature in the set of extracted features and a stored feature in the set of stored features,determine whether the payment document can be classified as one of the known payment document types associated with the matched stored feature based on the associated probability values of the matched stored feature by comparing the probability values associated with the matched stored feature with a predetermined threshold value; and
classify the payment document as the payment document type based on the determination;
a processing unit which is configured to;
process content of the payment document in view of the 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 camera of a mobile device; extracting a set of features from the image; comparing the set of extracted features against a set of features stored in a feature knowledge database, wherein a given feature in the set of stored features is associated with one or more probability values, and each of the one or more probability values represents a probability of occurrence of the given feature in a given payment document type within a set of known payment document types; and in response to a match between an extracted feature in the set of extracted features and a stored feature in the set of stored features, determining whether the payment document can be classified as one of the known payment document types associated with the matched stored feature based on the associated probability values of the matched stored feature by comparing the probability values associated with the matched stored feature with a predetermined threshold value; classifying the payment document as the payment document type based on the determination; and processing content of the payment document in view of the payment document type. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
