Implemented Loopy Belief Propagation [wiki], which is a more general optimization approach for Markov Random Field [post 1] [post 2]. Different from Graph Cut, it can be extended easily for non-grid graphs and non-binary cases. Here are some experiment results on …

In the previous post, we've seen applications of MRF in image restoration. This post will illustrate some more insights on MRF and graph-cut, a fast solution for global optimal.

MRF, graph, and graph cut

In the last blog post, we built a graph …

MRF for image restoration

Actually we discussed how to use MRF for image restoration before. Here we'd like to talk more about how an image restoration problem can be formulated as MRF and how to solve it.

Given an observed (noisy and possibly corrupted) image $Y$, how to recover the …
