Fractal image compression allows fast decoding but suffers from long encoding time. By mapping similar regions within an image in the wavelet domain, we can use biorthogonal wavelet transform coefficients to find mappings which are identical to conventional blockwise mappings,thus the time consuming encoding process will improved by wavelet based hierarchical interpretation. We apply our methods to encode video sequence of digital image, in our scheme, the encoding process ID done for image pieces or motion vectors from the predecessor. The result shows a relatively low frame rate, since our target is transmitting video sequence in the level of requirements in ITU-T H.324 or the V.34 modem physical layer.
