摘要
目的探讨使用油墨法捺印指纹样本汗孔特征的稳定性。方法用软件Image-Pro Plus 6.0对指纹图像选取的特征点进行测量和统计分析。结果变异系数绝大部分小于5%。结论油墨捺印方法能够稳定、客观地反映指纹汗孔特征。
Objective To study the stability of pore characteristics tances of pores in fingerprint were measured and the data were analyzed with eient of variation for distances between pores was less than 5 %. Conclusion and can be used in casework. of fingerprint printed with ink. Methods statistics software. Results The most of The pore characteristics printed with ink The dis- the coeffi- are stable
