Expressive line drawings of human faces from range images被引量：2
《Science in China(Series F)》2009年第2期295-307,共13页HUANG YueZhu MARTIN Ralph R. ROSIN Paul L. MENG XiangXu YANG ChengLei 
Supported by the National Basic Research Program of China (Grant No.2006CB303102);the National Natural Science Foundation of China (Grant Nos.60473103 and 60703028)
We propose a novel technique to extract features from a range image and use them to produce a 3D pen-and-ink style portrait similar to a traditional artistic drawing. Unlike most previous template-based, component-bas...

A new fast algorithm for computing the distance between two disjoint convex polygons based on Voronoi diagram
《Journal of Zhejiang University-Science A(Applied Physics & Engineering)》2006年第9期1522-1529,共8页YANG Cheng-lei QI Meng MENG Xiang-xu LI Xue-qing WANG Jia-ye 
Project supported by the National Nature Science Foundation of China (Nos. 60473103 and 60473127) and the Natural Science Foundation of Shandong Province (No. Y2005G03), China
Computing the distance between two convex polygons is often a basic step to the algorithms of collision detection and path planning. Now, the lowest time complexity algorithm takes O(logm+logn) time to compute the min...
