1. A computer-implemented image processing method, the method comprising:
- generating a collection of gradient data associated with a first image;
assigning pixels within the first image into a set of cluster features based on gradient magnitude as reflected in the collection of gradient data; and
storing the set of cluster features.

Abstract
A method for performing image recognition is disclosed. The method includes obtaining a collection of pixels and grouping at least some of the pixels into a set of cluster features based on gradient magnitude. For each cluster feature in the set, statistical variables are generated. The statistical variables represent a collective property of the pixels in the cluster feature. The statistical variables are utilized as a basis for comparing the collection of pixels to a different collection of pixels.

- 19. A computer-implemented method for performing image recognition, the method comprising determining the relative similarity of a first image to a second image, wherein determining comprises comparing cluster features associated with the first image to cluster features associated with the second image, and wherein the cluster features associated with the first and second images are derived based on pixels that have been grouped together based on gradient magnitude.
