English Description：
In image processing, considering fields like remote sensing and medical applications, Speckle (Multiplicative) noise dominates which affects the valuable features and important information of the image. To denoise an image, various transforms are used. But they are not efficient in case of preserving the edges and other essential features of an image which is the important factor in image processing for Image denoising. In image processing image is corrupted by different type of noises. But generally medical image is corrupted by speckle noise. So image de-noising has become a very essential exercise all through the diagnose. Noises are of two type additive and multiplicative noise. Speckle noise is multiplica
