AN ALGORITHM OF POLYGONAL APPROXIMATION FOR FEATURE CALCULATION

WU Zhonghai (Institute of Computer Science and Technology, Peking University, Beijing 100871 )ZHANG Xinggong; YE Chengqing; PAN Yunhe (State Key Laboratory of CAD/CG, Zhejiang University, Hangzhou 310027)  
Polygonal approximation is an important way to speed up feature calculation. This paper offers an efficient and definitive algorithm of polygonal approximation. It provides tolerance as an interactive parameter for various requirements of applications. It can process open-end curves with some modification. This algorithm has been used in three-latitude recognition of a body and analysis of speech frequence, and get good performance.
