SYSTEMS, METHODS, AND DEVICES FOR IMAGE MATCHING AND OBJECT RECOGNITION IN IMAGES USING FEATURE POINT OPTIMIZATION

摘要

An image matching technique locates feature points in a template image such as a logo and then does the same in a test image. Feature points of a template image are determined under various transformations and used to determine a set of composite feature points for each template image. The composite feature points are used to determine if the template image is present in a test image.

1. A computer-implemented, implemented by hardware in combination with software, the method comprising:
(A) producing multiple template images from a particular template image; (B) for each of said multiple template images and for said particular template image determining a corresponding set of feature points; (C) determining a composite set of feature points from feature points associated with each of said multiple template images; and (D) associating said composite set of feature points with said particular template image.
