Methods for mobile image capture and processing of documents
DCFirst Claim
1. A method for mobile image capture and processing of financial documents, comprising:
- receiving an image of a financial document captured by a mobile communication device;
geometrically correcting the image to clarify a content of the image, wherein clarifying the content of the image further comprises;
generating a color icon from the image, wherein the color icon is generated so as to suppress color contrasts within the image of the financial document and to preserve color contrasts between the financial document and a financial document background;
generating a grayscale icon from the color icon by reducing the color of the color icon such that the color contrasts between the financial document and the financial document background are preserved; and
identifying corners of the financial document within the grayscale icon;
identifying the content on the corrected image of the financial document; and
extracting financial content from the corrected image which is related to processing of the financial document by a financial institution.

Abstract
The present invention relates to automated document processing and more particularly, to methods and systems for document image capture and processing using mobile devices. In accordance with various embodiments, methods and systems for document image capture on a mobile communication device are provided such that the image is optimized and enhanced for data extraction from the document as depicted. These methods and systems may comprise capturing an image of a document using a mobile communication device; transmitting the image to a server; and processing the image to create a bi-tonal image of the document for data extraction. Additionally, these methods and systems may comprise capturing a first image of a document using the mobile communication device; automatically detecting the document within the image; geometrically correcting the image; binarizing the image; correcting the orientation of the image; correcting the size of the image; and outputting the resulting image of the document.
