CRF vs MRF


Edwin Chen did a very nice tutorial on Conditional Random Fileds. CRF have been used in NLP and Computer Vision papers ( Two out of three papers I read yesterday were using CRF). Question the bothered me was what is exact difference between CRF and MRF? Where to use just MRF and where to use CRF?  For example Edwin Chen’s blog says every HMM is CRF, is there any such relationship between MRF and CRF?

There are few pointers to this answer, have a look at http://metaoptimize.com/qa/questions/4021/what-is-exactly-the-difference-between-mrf-and-crf
