In this paper, a novel method of sparse coding shrinkage based on independent component analysis is proposed to reduce speckle in polarimetric SAR Images. With soft-thresholding operator on polarimetric SAR image, this method reduces speckle effectively and preserves polarimetric properties. The experiment shows that the image edges are retained with the method and the speckle is removed effectively.
