Method for Comparative Analysis of Bullet Marks Based on the Multi-dimensional Feature Extraction

This paper presents the method for comparative analysis of 3D bullet mark data and proposes the technology of realizing accurate comparative analysis by extracting multidimensional features of bullet data. In our approach, the first step is to denoise the data, and then extract multidimensional feature, finally we make the comparison of coarse level to fine level. The experimental results demonstrate the effectiveness of the method.
