Novel speed-up strategies for non-local means denoising with patch and edge patch based dictionaries
In this paper, a novel technique to speed-up a nonlocal means (NLM) filter is proposed. In the original NLM filter, most of its computational time is spent on finding distances for all the patches in the search window. Here, we build a dictionary in which patches with similar photometric structures...
