Three-dimensional model study on local height
3维模型局部高度研究

In this paper a new feature point detection method for 3D meshes is proposed.This method serves as an important preprocessing step for a number of 3D applications including mesh simplification,3D shape matching,and viewpoint selection.Compared with similar algorithms recently proposed,the proposed method has two advantages: 1) our feature point detection algorithm is based on our new perceptual saliency measure,using the local height,rather than being based on traditional curvature.We assume that the percep...
