Abstract :
We address the problem of efficiently encoding video sequences. A new system is proposed that overcomes the temporal redundancy by a new block based motion estimation called the hybrid adaptive motion search algorithm (HAMS), different wavelet/wavelet packet types are used for decomposition of the error frames, then the coefficients are thresholded and encoded. The new system achieves a reasonable PSNR at good compression ratios
