  How to establish the matching (or corresponding) between two different 3D
shapes is a classical problem. This paper focused on the research on shape
mapping of 3D mesh models, and proposed a shape mapping algorithm based on
Hidden Markov Random Field and EM algorithm, as introducing a hidden state
random variable associated with the adjacent blocks of shape matching when
establishing HMRF. This algorithm provides a new theory and method to ensure
the consistency of the edge data of adjacent blocks, and the experimental
results show that the algorithm in this paper has a great improvement on the
shape mapping of 3D mesh models.
