Image compression algorithm based on the texture preservation


In this paper, we propose a modified SPIHT algorithm based on the Texture Preservation. First, make a pretreatment of piecewise linear transformation to the coefficients of designated high-frequency subbands. By the addition of this step, the small coefficients in texture subband to some extent can be retained. Then improved SPIHT algorithm's ability of… (More)
