Abstract

The available mesh feature lines extraction methods based on the differential geometry properties cannot describe the global semantic characteristics well. To solve the problem, this paper proposed a method of extracting semantic feature lines of mesh model based on saliency analysis and human attention mechanism. Firstly, the method used the spectral theory to construct a smooth three-dimensional datum of the mesh model, obtained the salient vertices of the mesh. And then the method used the directional attributes of the discrete Laplacian-Beltrami operators to construct the mesh semantic feature areas, extracted and optimized the skeletons of the feature regions, and obtained the semantic feature lines of the model finally. The method hasn't need to measure the local differential properties of the mesh at all, and the experimental results show that the method can accurately extract the semantic feature lines, which can describe the global meaningful features of the model well.
