ABSTRACT:
The present invention is directed to a method and device for encoding a group of video frames. According to the present invention, regions in at least one frame in the group are matched to regions in multiple reference frames. The difference between pixel values of the regions in the at least one frame and the regions in the multiple reference frames is calculated. The difference is transformed into wavelet coefficients. The present invention is also directed to a method and device for decoding a group of frames by performing the inverse of the above described encoding.
