Abstract
A method and system for contour-based motion estimation for use with video images. The invention establishes corresponding contours ( ) in two images ( ) in a sequence of images, determines a motion vector which includes how the first contour ( ) moved to become the second contour ( ), and transmits the motion vector of the contour ( ) in order to permit accurate display of the second video image ( ). Preferably, boundary lines are removed from the contours before a comparison is made. The invention is computationally efficient and economical from a data transmission point of view, while enabling the production of accurate image.
