Hi,
Is there any sample tutorial/code to understand RJMCMC in image segmentation? 
Initially, I want to understand how an image can be obtained from a probability 
distribution like a gaussian mixture...

Dear Marcus,

As others have pointed out, RJaCGH uses Reversible Jump MCMC to fit a 
non-homogeneous Hidden Markov Model to array CGH data, but it can be used for 
other applications too.
It can be easily adapted to homogeneous HMMs and even to mixed models. It also 
contains implementations of additional MCMC techniques such as delayed 
rejection or coupled parallel chains, so probably it is a good start for 
learning RJMCMC.
Hope it helps,
Oscar

Thanks a lot.
