Hybrid adaptive motion search with wavelet/wavelet packet based motion residual video coding
El.-S. Youssef, Ehab Sabry, Mohamed Essam Khedr · 2002
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.
