First Claim
Patent Images
1. A method comprising:
- selecting a set of paths in an image, wherein the set of paths includes at least one line of pixels in the image, and wherein a total number of pixels in the set of paths is less than half of a number of pixels in the image; and
identifying at least one feature pixel in the set of paths by comparing gradients for each of the pixels in the set of paths.

Abstract
A system, method, and computer program product are provided for implementing a search of a digital image along a set of paths. The method includes the steps of selecting a set of paths in an image and identifying at least one feature pixel in the set of paths by comparing gradients for each of the pixels in the set of paths. The set of paths includes at least one line of pixels in the image, and a total number of pixels in the set of paths is less than half of a number of pixels in the image.
