Abstract
A video signal encoding apparatus determines quasi-feature points on the current frame based on selected feature points on the previous frame. A predicted current frame is obtained based on a number of triangle regions formed by the quasi-feature points. After determining a frame difference signal by subtracting the predicted current frame signal from the current frame signal, a plurality of processing regions are selected from the frame difference signal based on the magnitude of average pixel difference values corresponding to the triangle regions. Only the selected processing regions are then encoded for transmission to thereby reduce a transmission rate. A video signal decoding apparatus comprises corresponding circuits for decoding the selectively encoded video signal.
