Fuzzy theory is introduced into the Markov random field model, a kind of algorithm for image segmentation based on fuzzy MRF model is put forward. Firstly the definition of membership function is given. Then fuzzy prior distribution and likelihood distribution are given. The specific steps of segmentation algorithm based on fuzzy MRF model are carried out. The simulation results show that the proposed segmentation algorithm based on the fuzzy MRF model can better deal with the problems of overlapped gray, partial volume effect, and low contrast. It also has more accurate segmentation effect.
