Examples in Context

  1. In this paper, an approach of vector quantization for high quality and low rate speech cooling is discussed.
  2. The experimental results show that PCA and correlation vector quantization can accelerate the encoding speed and increase the compression rate compared with the full search vector quantization, although the encoding quality degrades a little.
  3. Thus the application of this vector quantization in speech encoding can improve the quality of speech encoding.
  4. In comparison to classical full search vector quantization, the algorithm leads to power savings without image quality reduction.
  5. This article puts forward an improved LBG algorithm on the basis of the asymptotically optimal vector quantization theory ~ [ 4 ]. To obtain a quantizer with higher quality, the algorithm uses the method of codewords shifting which can ulteriorly diminish the average distortion.
