ABSTRACT:
A contour of an object in an image having one or more objects therein is reconstructed based on encoded contour data for the contour and a previously reconstructed contour for an object included in the image. The method, first, decodes the encoded contour data for a current contour to thereby provide a reconstructed current contour and checks whether the reconstructed current contour overlaps with any previously reconstructed contours. If none of the previously reconstructed contours overlaps with the reconstructed current contour, the method sets the reconstructed current contour as a currently reconstructed contour. If, otherwise, the reconstructed current contour overlaps with a previously reconstructed contour, the reconstructed current contour is modified not to overlap with the previously reconstructed contour and the method sets the modified contour as the currently reconstructed contour.
