Abstract

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 Preservation.
