| Abstract(in English) | This article proposes a new method for registering a surface of an organ in a 3D medical image with a surface mesh model of the surface. Each grid point of the surface mesh has probabilistic models of its position, the local deformation, and its local image pattern. For learning those probabilistic models, we compute a set of correspondences on each surface of sample data by using an entropy-based particle system. For the registration, we use a non-parametric belief propagation. The proposed method can estimate the probability density distribution of the position of each grid of the surface mesh. The proposed method was applied to some actual 3D medical images, and the results are presented in this article. |
