%X For the problem in vector quantization that the compression ratio is slow and image restoration result is not satisfactory,and according to the sparsity properties of the high frequency wavelet transform coefficients,the paper proposed a new method of categories quantization coding for image based on compressed sensing.Compared with the LBG vector quantization coding algorithm,simulation results demonstrate that the proposed algorithm improves the quality of the recovered image significantly.For the similar...
