Variable block size wavelet video coding
Vitor M. M. da Silva, Luis A. S. V. de Sa · 2002
A new and efficient video coding algorithm is described. It is based on the wavelet decomposition of video signals using orthonormal and biorthogonal filter banks. The motion compensated error images are represented by variable size blocks. To improve the coding efficiency and to minimize the border effects associated to the wavelet transform, a new quadtree based merging algorithm was developed. The results of two coding scenarios are discussed.>
