METHOD AND SYSTEM FOR FINDING A DOCUMENT IMAGE IN A DOCUMENT COLLECTION USING LOCALIZED TWO-DIMENSIONAL VISUAL FINGERPRINTS
First Claim
1. An image management method for storing, indexing, searching,:
- and/or retrieving image data comprising the steps of;
identifying keypoints in images, including keypoints in a query image of a query document and keypoints in potential target document images of a collection of potential target documents;
generating fingerprint information from the keypoints;
comparing the fingerprint information of the query image with fingerprint information of the potential target document images in the collection of potential target documents;
determining a best match between the fingerprint information of the query image and the potential target document images;
retrieving at least one target document image based on the determining step; and
at least one of displaying, printing, storing or transmitting the retrieved at least one target document image.

Abstract
An image management method and system provides for storing, indexing, searching, and/or retrieving image data. Keypoints are identified in images, including keypoints in a query image of a query document, and keypoints in potential target document images of a collection of potential target documents. Fingerprint information from the keypoints are generated, and the fingerprint information of a query image is compared with fingerprint information of potential target document images, found in the collection of potential target documents. A best match is determined between the fingerprint information of the query image and the potential target document images. At least one target document image is retrieved based on the determined best match. The retrieved at least one target image may then be displayed, printed or transmitted.

16. An image management system within a computer operable system for storing, indexing, searching, and/or retrieving image data comprising:
-
an identification module configured to identify keypoints in images, including keypoints in a query image of a query document and keypoints in potential target document images of a collection of potential target documents; a fingerprint generation module configured to generate fingerprint information from the keypoints; a comparison module configured to compare the fingerprint information of the query image with fingerprint information of the potential target document images in the collection of potential target documents; a matching module configured to determine a best match between the fingerprint information of the query image and the potential target document images; a retrieval module configured to retrieve at least one target document image based on the determining step; and at least one of an electronic display, a printer, a memory storage or a computer network to display, print, store or transmit the retrieved at least one target document image. - View Dependent Claims (17, 18, 19, 20, 21, 22)
