摘要

A speckle reduction by edge-preserving method to solve spaceborne SAR image's edge ambiguity after normal speckle reduction was developed. Based on joint several edge detection methods, the edge was detected from SAR image by using Haralick algorithm and general fuzzy operator. (GFO) 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. The new method was demonstrated by spaceborne SAR image. It is a good way for speckle reduction for SAR images.
