Computing Life

The motivation is, I am trying to move this blog to a linux machine. Anyway, in my old server, Windows Server 2008 is rather slow.

The procedures are very simple:

1. Install apache2, mono-complete,and libapache2-mod-mono.
2. Download DotNetBlogEngine 1.6 zip file, extract it, and then copy files into /var/www …

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 …

Is there a language/platform which can suit all the applications?

C#, my favorite language, with perfect editing/debugging environment and advanced ML libraries. But, the libraries are not optimized deliberately. In a competition with MATLAB to sort 0.5 billion numbers, MATLAB only needs 17s using 6 cores and …
