用形态学中骨骼化方法实现了图像细化，为后续工作如特征点提取提供了良好的素材-Method with skeletal morphology achieved thinning, for the follow-up, such as feature extraction provides a good material

人脸稀疏分类研究，基于DD-DT CWT多字典的人脸特征稀疏分类方法-Face thinning classification, based on DD-DT CWT dictionary feature sparse classification method

本文设计了一套指纹图像预处理和指纹特征提取算法, 利用方向滤波的方法对原始图像进行增强,使用改进的细化算法进行细化, 最后基于脊线跟踪的方法, 用改进的算法更为简洁而有效地避免了各种伪特征。设计的算法经Matlab 实现, 实验效果良好。-Designed a fingerprint image and fingerprint feature extraction algorithm using directional filtering the original image enhanceme

The popular Biometric used to authenticate a person is Fingerprint which is unique and permanent throughout a person’s life. A minutia matching is widely used for fingerprint recognition and can be classified as ridge ending and ridge bifurc
