Image de-noising plays an important role in satellite communication and signal processing applications. This paper presents significant work in the area of image de-noising. For better de-noising in SAR images, we perform Non-local means (NLM) technique and have used few filters such as min-max filter and average filter. By performing the above technique, the de-noising ratio is increased, at the same time the image resolution is enhanced. All these filtration transform techniques were observed on multiplicative noise in synthetic aperture radar (SAR) images. The performance of NLM is compared with previous techniques in terms of quality parameters like Peak signal to noise ratio(PSNR), Mean square error(MSE), Percentage of Spoiled Pixels (PSP), structural similarity index measure (SSIM). |
