查询词典 speckle

Based on joint several edge detection methods, the edge was detected from SAR image by using Haralick algorithm and general fuzzy operator algorithm, and then the detected edge was subtracted from SAR image, then Lee filter was used to filter the speckle image without edge, at last the edge was added to the filtered image.

常规滤波算法在滤除噪声的同时也带来了图像边缘模糊问题，利用多种检测图像边缘算法的有机组合，首先提取出图像边缘，然后将边缘从图像中剔除，对剩下的无边缘噪声图像用改进Lee滤波法进行噪声抑制，再把边缘图像加入，最后得到了能保持边缘的SAR图像相干斑滤除图像。
