改进的快速SPIHT 算法.针对原算法的不足引入了“最小阈值”和“最小输出位”,同时改变了原算法的扫描顺序,降低了算法的复杂程度,并使其更有利于并行优化处理。实验证明,改进后的算法减少了编解码过程中的存储容量和时间消耗,而重建图像的峰值信噪比和人眼视觉效果与原算法相当。-improved fast SPIHT. Against the original algorithm of the introduction of the "minimum threshold" and "the smallest output ", and also changed the original algorithm scanning sequence, reducing the complexity of the algorithm, and make it more conducive to optimizing the parallel processing. Experiments show that the improved algorithm to reduce the codec in the process of storage capacity and time consumption, and reconstruction in PSNR and the human visual effects and the original algorithm. 下载
