基于频谱分析的指纹图像奇异性检测
A Method of Singularity Detection in Fingerprint Images Based on Spectrum Analysis
【摘要】 针对指纹图像奇异性检测问题,分析了现有检测方法存在的问题,提出了用方向二值图进行频谱分析来检测奇异性的新方法。新方法检测正确率为90%。
【Abstract】 Detection of singularity of fingerprint images is very important.In this paper through analyzing some short-coming of the singularity detection method,a new approach for detecting singularity based on spectrum analysis of an orientation field binary map is proposed.The method is tested using fingerprint images and the recognition rate is90%.
