Classification: CPC G | IPC G

Claim 14:
15. A non-transitory computer readable medium storing instructions that, when executed by one or more processors, cause the one or more processors to:
detect a first set of feature points within a first frame;
generate a first image that indicates locations of the first set of feature points detected within the first frame, 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;
generate a second image that indicates respective bounded neighborhoods each of which corresponds to a neighborhood surrounding one of a second set of feature points detected based on a second frame, 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.
