Adaptive orthogonal filter bank trees for encoding of motion-compensated frame differences

An algorithm for adaptive orthogonal filter bank trees for encoding of motion-compensated frame differences is presented. The proposed method is based on the hybrid video coding scheme. For frame prediction, overlapped block motion compensation is applied. The prediction error frames are encoded using an adaptive wavelet packet algorithm based on a two-channel orthogonal FIR filter bank. Haar filters and minimum-phase Daubechies filters are employed. The signal boundaries are decomposed by means of optimized boundary filters. The proposed method is compared to the DCT-based hybrid video coding scheme.
