Aiming at the problem of coarse footmark surface with severe noises, based on the in-depth analyzing geometrical relationship and differential characteristics of the three-dimensional footmark impressing surface, we propose a principal curvature and principal direction based impressing surface segmentation algorithm and a multi-scale fusion algorithm to segment the stereo footmark.

针对立体赤足迹表面粗糙、噪声严重的特点，深入分析立体足迹三维表面的几何关系和微分特性，提出了基于曲面主曲率和主方向的立体足迹压力面分割算法和多尺度融合算法，分割结果理想并与领域知识吻合。4。

Segmentation and extraction of the target feature points from the unregistered, noisy data set of human body scanning and measuring are discussed. We have fitted the noise scanned data line with KS principal curve, which is based on the K-means theory. The crossing zero of curvature was used to segment and estimate the position of target feature points. And optimization scheme named variable fuzzy partition is also presented to improve the searching for local feature area.
