A survey on: De-speckling methods Of SAR image

For the past five decades, de-speckling of Synthetic Aperture Radar (SAR) images is one of the hottest research areas. This research work presents the comprehensive survey about the various de-speckling methods. After studying this survey, the researcher comes to know the various de-speckling techniques also with merits and demerits of each method and the different parameters used to evaluate the quality of de-speckled image. Hence, it becomes easier to select which is the suitable technique for de-speckling and to find out various purposes which help for different types of de-speckling accordingly.
