用于频谱细化，是《matlab在振动信号处理应用》一书中的实例-Spectrum refinement matlab vibration signal processing applications, " a book instance.

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
