Distinguishing 3D Surface by Means of Analyzing Curve Shape
基于曲线形状分析的三维表面识别

This article discusses analyzing curveshapeand distinguishing m ethods on 3D surface. Considering needsofrecog nizing 3D footm arks in detective w ork, this paper poses draw ing features ofequal value curves ofthree dim entionalsurface, the analysis for space structure and auto regresive spectrum ofthe curve shape,and a fuzzy distinguishing m ethod on the base ofthe above analysis. Itis proved by experim ents thatthe m ethod is very effective on recognizing 3Dsurface.
