ABSTRACT:
A method for tracing a contour of an object in an image of a video signal, the image including object pixels and background pixels, indexes each of the background pixels; detects contour pixels; groups the contour pixels to thereby provide one or more groups of contour pixels, each contour pixel in a group adjoining one or more background pixels of a same background index; and traces the contour pixels on a group-by-group basis.
