Classification: CPC G | IPC G

Claim 7:
8. A computer vision system comprising:
a detection circuit configured to detect a first set of feature points in a first frame; and
a feature point identification circuit coupled to the detection circuit and configured to:
receive the first set of feature points from the detection circuit;
generate a first image that indicates locations of the first set of feature points, wherein the locations of the first set of feature points are indicated in the first image by a first binary value and a remainder of the first image is indicated by a second binary value;
receive a second set of feature points detected based on a second frame;
generate a second image that indicates respective bounded neighborhoods each of which corresponds to a neighborhood surrounding one of the second set of feature points, wherein the respective bounded neighborhoods are indicated in the second image by the second binary value and a remainder of the second image is indicated by the first binary value; and
compare the first image to the second image to generate a third image, wherein locations of a subset of the first set of feature points excluded from the respective bounded neighborhoods are indicated in the third image by a binary value different from a remainder of the third image.
