Markov Models for Image Labeling

Figure 7

An example of image denoising. (a) is the original noisy image. (c) is the denoising result by BP using pairwise interaction [5]. (b) is the result by BP with the learned 2-by-2 model. The results no longer exhibit any piecewise constancy. Not only edges are preserved, but also smoothly varying regions are preserved better than those with higher-order clique [39].
