ABSTRACT:
A method and apparatus for encoding and transmitting a sequence of image frames employ a measure of motion displacement for generating a motion compensated image. The motion compensated image, together with an error signal, provides the receiver with full detail regarding the next frame of a sequence. In some instances, however, the motion displacement data is inaccurate for portions of the next image frame. In those instances, the method and apparatus determine whether filtering of a portion of the motion compensated image provides a lower error energy for the resulting prediction of the image. If a lower error energy can be achieved by low-pass filtering, the data regarding the additional processing of the motion compensated reconstructed image is transmitted to the receiver.
