The Application of Wavelet Theory in Analysis of Surface Topography of Rifle Worn Marks

Abstract:

This paper makes decomposition of the profile curve of rifle worn marks by the wavelet transform, which can make its complicated structure feature to be clear. By reconstruction, the noise in the process of collecting and distraction can be removed, which makes the calculated fractal dimension more reliable. The research shows that wavelet transforms of profile curves can not only describe the surface topography of rifle worn marks, but also exhibits its essence characteristics. The paper provides a new method of quantitative examination and classification identification for rifle worn marks.
