摘要：In image processing, restoration and noise reduction is expected to improve the qualitative inspection ofthe image and the performance of quantitative image analysis techniques. Different approaches for imagerestoration have been proposed, each of which has its own advantages and limitation. This paper combinesthe adaptive median filtering technique and the non-local means filtering algorithm for image denoisingsalt and pepper noise to yield a considerably high PSNR. The Non-Local means filter assumes that animage contains an extensive amount of self-similarity and exploits it to denoise an image. The analysis ofthe statistical results is presented in simulations done using MATLAB to demonstrate the advantages andlimitations of using the proposed method over other existing techniques.
