3D model simplification method with lossless sharp regions

In the course of 3D model simplification, the sharp regions are required to be kept lossless in some specific areas such as medical stereo image processing, 3D film industry and digital certification. Current simplification algorithms only focus on the fidelity of the whole model, ignoring the significance of the integrity of the sharp regions. This paper presents a novel algorithm to combine mesh segmentation and mesh simplification. Experimental results show that the proposed algorithm keeps the sharp regions lossless while ensuring the high fidelity of the whole model.
