Image denoising can be classified into (1) pixel domain and (2) frequency domain. In pixel domain, each pixel in the noisy image is modified with a view of removing noise from the image. As most of the noises are in the high frequency domain, the denoising algorithm generally implement some kind of low pass filtering. Gaussian
