An approach for quality assessment of the filtered images was proposed . after qualitative and quantitative assessment , some conclusions have been drawn : ( 1 ) spatial filters are affected greatly by filtering window size , the size of 5 5 presents best result ; ( 2 ) enhanced frost filter , enhanced lee filter and gamma - map filter smooth the speckle noise well with a small sacrifice of losing texture details and narrow edges , which are better than other popular spatial filters ; ( 3 ) the results show that the proposed filter retains texture and edges well , so more researches are expected
通过对jers - 1sar图像的各种滤波图像进行了目视评价和指标比较，得出如下结论: ( 1 )各种空间滤波器受滤波窗口的影响很大， 5 5大小的滤波窗口滤波效果较好； ( 2 )对比各种常用的空间滤波器，增强的frost滤波器、增强的lee滤波器和gamma - map滤波器在去噪和纹理、结构特征保持方面效果最好； ( 3 )小波滤波方法在保持sar图像纹理细节方面表现出了很好的优势，还有待进一步研究。
