Edge preserved smoothing techniques has gained importance for the purpose of image denoising. A good edge preserved filtering is given by nonlocal-means filter than any linear model based approaches.The contributions are in two fold. First, this paper explores a refined approach of nonlocal-means filter by using robust estimation function rather than the usual exponential function for its weight calculation. Here the filter output at each pixel is the weighted average of pixels with the… CONTINUE READING
