Image Compression Algorithm Based on the Texture Preservation

摘要：

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 label important coefficients. Experiments show that even at low bit-rate modified SPIHT algorithm has good performance on the Texture
