Abstract
A video signal coding system employing a segmentation technique segments a video frame signal into regions to generate contour and texture information of each region and detects continuous boundaries located between adjacent regions. The contour and the texture information of each region and the boundary information of the continuous boundary are encoded to provide an encoded video signal. The video signal coding system calculates a mean value of pixels in two adjacent regions of each side of a continuous boundary and updates each pixel value within a predetermined distance from a continuous boundary with the mean value.
