中文摘要：

基于多分辨分析,从特征的统计分布、特征能量以及特征变化方向等方面给出了图像的特征信息度量方法。理论分析表明,该方法具有科学性。实验结果显示,该方法不仅对遥感和医学类图像是可行的,而且对于自然图像,当特征信息保持较好的情况下峰值信噪比下降6～7dB时图像的视觉效果仍不会降低。

英文摘要：

A measurement method of image characteristic information is introduced based on multiresolution analysis.The characteristic distribution,characteristic energy and the variety directions of the characteristic information are utilized in the scheme.Experimental results show that the method is feasible not only to such special images as remote sensing images and medical ones,but also to natural images.And the visual quality is still very well when the peak signal-to-noise ratios descend 6～7 dB and the characte...
