Abstract: Automatic and accurate boundary estimation is one of the crucial issue in 3D mesh segmentation. To provide a theoretical basis for automatic segmentation, the paper proposes a new method for estimating 3D mesh boundary probability. In this method, a few boundary points are manually marked and considered as energy sources, in which the energy will flow to the surrounding area. As the convexity values of 3D mesh points are different, the energy values finally reaching to each point are different and can be used to estimate the possibility of boundary. Experimental results show that the method is effective to find more boundary points simply using a small number of boundary points and is able to provide a sound theoretical basis for automatic 3D mesh segmentation.
