指纹预处理中的增强算法，matlab上面实现hong的gobar算法。

预处理后将得到一幅宽度为一个像素的细化二值图像，然后通过特定的端点和交叉点的特征进行指纹匹配。论文中采用MATLAB编程实现全部算法。-After pretreatment of a width of one pixel to obtain a binary image thinning, and through specific endpoint and the intersection of the characteristics of the fingerprint matching. T

自己编写的形态学滤波预处理指纹图像matlab编程，包括n*n二值腐蚀、膨胀、开、闭操作。-I have written a fingerprint image preprocessing morphological filtering matlab programming, including n* n binary erosion, dilation, opening and closing operation.
