We propose the use of surface torsion to represent local features on the original model  and consider it as an additional weight factor when calculating the edge contraction cost during the simplification process. The approximations of the original deforming models are generated progressively from the first frame to the last one. Based on the edge contraction sequence in the previous frame  the contraction order in the current frame is adjusted according to the deformation degree. Our approach is fast  easy to implement  and as a result good quality approximations with well-preserved fine details can be generated at any given frame. 2010 IEEE.   An improved method for generating multiresolution animation models (EI CONFERENCE) 会议论文  OAI收割 2009 11th IEEE International Conference on Computer-Aided Design and Computer Graphics, CAD/Graphics 2009, August 19, 2009 - August 21, 2009, Huangshan, China 作者:  Zhang S. 收藏  |  浏览/下载：36/0  |  提交时间：2013/03/25 In computer graphics  animated models are widely used to represent time-varying data. In this paper  we propose an improved method to generate multiresolution animation models. We use a curvature sensitive quadric error metric (QEM) criterion as our basic measurement  which can preserve local features on the surface. We append a deformation weight to the aggregated edge contraction cost for the whole animation to preserve areas with large deformation. At last  we introduce a mesh optimization method to deal with the animation sequence  which can efficiently improve the temporal coherence and reduce visual artifacts. The results show our approach is efficient  easy to implement  and good quality progressive animation models can be generated at any level of detail. 2009 IEEE.   Combining local features for robust nose location in 3D facial data 期刊论文  OAI收割 PATTERN RECOGNITION LETTERS, 2006, 卷号: 27, 期号: 13, 页码: 1487-1494 作者:  Xu, Chenghua;  Tan, Tie;  Wang, Yunhong;  Quan, Long 收藏  |  浏览/下载：52/0  |  提交时间：2015/11/08 nose tip location  local surface features  local statistical features  included angle curve  SVM
