摘　　要：视觉特性的小波零树编码,是将小波图像系数进行视觉加权,对高频和低频子带并分别编码,实验结果表明,该方法在保证恢复图像具有良好的视效果前提下,进一步提高了压缩比。The Embedded Zerotree Wavelets Coding based on Human Visual System,give different perceptual weights to the corresponding wavelet coefficient,and encode the coefficient separately of sub-bands in high frequency and low frequency.The experiment results indicated that while assuring the most crucial coefficient on the vision of priority encoding,it could improve the image restoration quality as well.

关 键 词：小波变换 图像编码 零树 人眼视觉特性
