AUTOMATED LABELING OF FEATURES IN VIDEO FRAMES

Systems and methods for automatic labeling of unlabeled video frames from a video sequence, based on known features in other frames in the sequence. An unlabeled video frame and a labeled video frame are received by an identification module. The unlabeled frame and the labeled video frame are temporally close to each other within the video sequence and preferably temporally adjacent. The identification module recognizes labeled features within the labeled frame. The identification module then identifies multiple potential features within the unlabeled frame. A comparison module then compares each potential feature in the unlabeled frame to the recognized labeled feature in the labeled frame. If a match is found, a labeling module applies a label to the potential feature in the unlabeled frame, thereby producing a newly labeled frame. The labeling process repeats until all frames in the sequence have been labeled.
