In this paper a new very low bit rate scalable encoding principle is presented. It is based on hierarchical triangular mesh encoding combined with triangle based DCT coding. Affin...
The modified Differential Pulse Coded Modulation (DPCM) codec with multi-rate processing has been shown to able to code source with monotonically decreasing spectrum efficiently a...
Efficient compression algorithms generally use wavelet transforms. They try to exploit all the signal dependencies that can appear inside and across the different sub-bands of th...
