Abstract: A method and an apparatus for object recognition are provided. The method includes: receiving a video including a plurality of frames, and separating the frames into a plurality of frame groups; executing object recognition on a specific frame in each of the frame groups to recognize at least one object in the specific frame; dividing a bounded area of each object into a plurality of sub-blocks, and sampling at least one feature point within at least one of the sub-blocks; and tracking each object in the frames in the frame group according to a variation of the feature point in the frames in the frame group.
