基于CxImage库的SAR图像Speckle噪声抑制

Abstract

Abstract:

The Speckle noise suppression for Synthetic Aperture Radar (SAR) images is an important part in the SAR image information processing.The traditional Speckle denoise algorithm is integrated in a processing module.But the codes of the software are encapsulated so that it affects the secondary development.In this paper,an integrational application method for spatial self-adapting filtering based on CxImage open source image library is proposed.CxImage image library is linked into the MFC application framework,and then its powerful image management,maintenance,processing functions are used to maintain and manage the SAR images.the classic space-domain self-adapting filtering methods are further integrated to do the speckle noise filtering of ERS-2 PRI SAR images.the appropriate evaluation parameters of filtering effect are selected,and the filtering results are compared,and finally the pros and cons of each filtering algorithm applied to SAR image filtering are concluded.
