Fig. 7From: Optimal graph edge weights driven nlms with multi-layer residual compensationDenoising results of depth image (teddy) with the noise variance \(\sigma = 50\) [top], the difference between the original depth images and the filtered images [middle], and zoom-in image [bottom]. From the left (a) to right (g) are: the original image, the noisy image, the results obtained by NLM, BM3D, OGLR, ADnet and the proposed method respectivelyBack to article page
