In this paper, a new multi stage vector quantization with energy clustered training set is proposed for color image coding. The input image is applied with
The quantization of LSP parameters is one of the most important subjects in the low bit rate speech coding.In this paper,tree seached multi-stage vector quantization(TS-MSVQ)is invstigated.The aim of TS-MSVQ is to reduce the computational complexity.First,the weight coefficient of LSP distan...
The steps of codebook generation and vector encoding of the various embodiments of the method for compressing a continuous data flow have been implemented using the Successive Approximation Multi-stage Vector Quantization (SAMVQ) technique disclosed by the inventors in U.S. patent application Ser. No...
PURPOSE:To suppress the increase of the quantization distortion while keeping the small memory capacity for the multistage vector quantization. CONSTITUTION:A coder checks whether the output points to original exist are confirmed or not at the 2nd and consequent stages of the multistage vector ...
The proposed scheme is called multi-stage hierarchical address vector quantization and it combines the concepts of multi-stage VQ (MSVQ), hierarchical VQ (HVQ) and address VQ (AVQ). Its encoder consists of several stages where the HVQ or AVQ is applied while the larger image blocks are ...

For example, the LPC processing component (435) converts LPC values to a line spectral pair [“LSP”] representation, and the LSP values are quantized (such as by vector quantization) and encoded. The LSP values may be intra coded or predicted from other LSP values. Various representations,...
