Particle System Based Adaptive Sampling on Spherical Parameter Space to Improve the MDL Method for Construction of Statistical Shape Models

Figure 2

An example of the estimated probability distribution for vertices of parameterized meshes on the unit sphere. The red regions show where probabilities of vertices existing in those regions are high, and the blue regions show where the probabilities of vertices existing in those regions are low. The estimated probability distribution is able to reflect how triangles of parameterized meshes are distorted. For example, high probability (red color) means that triangles in those regions are shrunk, and low probability (blue color) means that triangles in those regions are expanded.
