Various embodiments are disclosed for performing object tracking. One embodiment is a method for tracking an object in a plurality of frames, comprising obtaining a reference contour of an object in a reference frame and estimating, for a current frame after the reference frame, a contour of the object. The method further comprises comparing the reference contour with the estimated contour and determining at least one local region of the reference contour in the reference frame based on a difference between the reference contour and the estimated contour. Based on the difference, at least one corresponding region of the current frame is determined. The method further comprises computing a degree of similarity between the at least one corresponding region in the current frame and the at least one local region in the reference frame, adjusting the estimated contour in the current frame according to the degree of similarity, and designating the current frame as a new reference frame and a frame after the new reference as a new current frame. |
