Abstract
An apparatus for encoding a contour of regions contained in a video signal comprises first and second segmentation blocks for segmenting previous and current frame into a number of regions to generate previous and current contours, a prediction parameter calculation block for generating prediction parameters based on the previous and current contours, and the previous and current frames, a contour prediction block for constructing a predicted current contour by transforming the previous contour based on the prediction parameters, an error detection block for detecting deviation points lying on portions of the predicted current contour that deviate from the current contour, thereby generating the deviation points and corresponding displacements to the deviation points, and a contour coder for encoding the deviation points and the displacements together with the prediction parameters.
