First Claim
Patent Images
1. A method for performing feature tracking on image frames, comprising:
- initializing first and second feature points on a first image frame;
generating candidates for the first and second feature points on a second image frame; and
generating candidates for the first feature point on a third image frame from information about candidates for the second feature point on the second image frame, wherein the first, second, and third image frames generate a video sequence.

15. A machine-readable medium having stored thereon sequences of instructions, the sequences of instructions including instructions which, when executed by a processor, causes the processor to perform:
-
initializing first and second feature points on a first image frame; generating candidates for the first and second feature points on a second image frame; and generating candidates for the first feature point on a third image frame from information about candidates for the second feature point on the second image frame, wherein the first, second, and third image frames generate a video sequence. - View Dependent Claims (16, 17, 18, 19)
