基于8邻域编码逐像素跟踪法的指纹细节特征提取算法

研究并实现基于8邻域编码逐像素跟踪法的细节特征提取算法。该算法能有效提取细化后指纹图像中的端点和分叉点,通过回朔跟踪法,能有效去除图像中的伪特征点。实验结果表明该算法较大幅度提高了特征提取的速度,并能够较准确的滤除伪特征点,缩短了图像后处理时间,可以满足实际应用的需要。

Minutiae Extraction in Fingerprint Images Based on 8 Neighborhoods Region Coding Pursue Pixe

Minutiae extraction in fingerprint iImages based on 8 neighborhoods region coding pursue pixel method is studied and realized. It can realize the image after melts carefully for fingerprint in end points and bifurcation point go on effective draw, and through returning slot the fake feature point in image go to wipe off. Test result to show that this method greater improve the speed that drawn, reduction imagery processing time, can satisfy the needs of actual application basically, and can be more exact to strain the fake feature point. The experiment indicated, a suit of arithmetic operational speed that this paper puts forward rapid, can draw feature efficiently, method is simple and effective, and the algorithm is simple, is easy programming realization.
