A Residual-Based Kernel Regression Method for Image Denoising

Figure 8

Performance of different denoising methods is compared on a color image with real noise; (e)–(g) show the residual between given noisy image and the respective estimates. (a) Real noisy image; (b) bilateral filter; (c) structure adaptive filter; (d) the proposed method; (e) bilateral filter; (f) structure adaptive filter; (g) the proposed method.
