While capturing SAR images, a special type of noise can degrade its quality by blurring the detail part of image and that noise is usually multiplicative speckle noise. The process of elimination of that speckle noise is called despeckling SAR images which helps to preserve details of image, after removing noise factor, like structures, edges, corners etc. In this paper, the combination of frost filter and bilateral filter is used. Initially, the Frost filter is applied on noisy SAR image and edge enhancement is performed on the output of frost filter. Furthermore, Haar wavelet is applied on output of frost filter and calculates the median of diagonal detailed part of the image. Calculate the standard deviation and sigmar value. Apply the bilateral filter on the output of frost filter. Calculate the method noise for restoring that part of noisy image which is unfiltered. At last perform the element-wise multiplication of output of the method noise and edge enhancement. The quality of image is compared on the basis of performance measures like PSNR, MSE, MSSIM and UIQI. The performance is compared with all other existing filters and results show that the proposed method has brilliant performance.
