嵌入式系統中SPIHT算法改進的研究: 本文在重點分析研究SPIHT算法的基礎上,結合現有技術提出一種改進的SPIHT算法.改進的SPIHT算法通過采用提升小波變換、結合人眼視覺特性、對算法的分集排序過程進行優化等措施,進一步提高壓縮性能,而且圖像復原質量較好.-SPIHT algorithm for embedded systems to improve the research: In this paper, the focus of analysis in the SPIHT algorithm based on a combination of existing technologies to improve the SPIHT algorithm. SPIHT algorithm to improve through the use of the lifting wavelet transform, combined with human visual characteristics, the algorithm Diversity order to optimize the process, such as measures to further enhance the compression performance and image quality of a good recovery.
