Systems for mobile image capture and processing of checks
DCFirst Claim
1. A system for image capture and processing of financial documents, comprising:
- a mobile device including;
an image capture device configured to capture a color image of a financial document,a processor configured to;
detect the financial document in the color image, andgeometrically correct the color image and generate a gray-scale image, anda transmitter configured to transmit the gray-scale image to a server; and
a server configured to receive the gray-scale image from the mobile device and to;
binarize the gray-scale image to produce a bi-tonal image,correct the orientation of the bi-tonal image, andcorrect the size of the bi-tonal image.

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.

11. A system for image capture and processing of financial documents, comprising:
-
a mobile device including; an image capture device configured to capture a color image of a financial document, and a transmitter configured to transmit the color image to a server; and a server configured to receive the color image from the mobile device and to; detect the financial document in the color image, wherein the server is configured to detect the financial document in the color image by; converting the color image into a smaller color image; performing color depth reduction on the smaller color image; and determining document corner positions for the financial document in the smaller color image and geometrically correct the color image and generate a grey-scale image, binarize the gray-scale image to produce a bi-tonal image, correct the orientation of the bi-tonal image, and correct the size of the bi-tonal image. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
