MATLAB源码，preprocessing.m: preprocess the picture including:Wiener filter; meddle value filter, change a gray picture to a binary one and then get the skeleton. centralizing.m: input the source picture output the core point of the fingerprint. samfun.

image_binaryzation.m : 图像二值化主函数，调用otsu、kittler otsu.m : 类判别分类法（otsu全局二值化算法） kittler : 最小分类错误(minimum error thresholding)全局二值化算法 image_refining.m : 图像细化主程序，调用otsu、refining refining.m : 计算骨架的一种实用方法对图像进行细化 coins.bmp lenna.bmp woman_

利用IMA算法，提取三维模型的骨架，希望对大家有用！-It contains the sources of the C-implementation of the IMA skeleton of a 3D data set as described in the paper:W. H. Hesselink, J. B. T. M. Roerdink: Euclidean skeletons of digital image and volume data in linear time b

它是基于MATLAB的骨架提取方案，编写了几个M文件，只是一个小程序，-It is based on MATLAB skeleton extraction program, write a few M-file, just a small program,
