图片（信息熵、对比度、平均亮度、清晰度）

说明：  指纹图像预处理、特征提取、特征匹配的matlab程序及处理结果(Fingerprint image preprocessing, feature extraction, feature matching matlab program and processing results)

时移相位差校正法，通过时移，进行前后两次FFT分析，利用离散频谱对应峰值谱线的相位差以求出频率和相位校正量。(Phase difference correcting method by time-shifting. Make two FFT analysis before and after the time-shifting,and make use of the phase difference of the peak spectral lines to get frequency and phase correction amount.)

vc++图像处理原程序：图片亮度增减源代码(vc original image processing procedures : Photo brightness change source code)

实现LLE算法，本算法是改进的LLE算法，主要是针对人脸图像的。()

我自己做的一个bmp文件进行24位真彩转256灰度和二进制的程序，并能用sobel算法，识别物体的边界。 (I myself make a bmp file for 24-bit true color to 256 gray-scale and binary procedures and sobel algorithm can be used to identify object boundaries.)

本程序实现医学图像的增强，实验显示，处理后的医学图像轮廓清晰，可识性较好。(This procedure to achieve medical image enhancement, experiments showed that the treated medical image outline a clear, identifiable better.)

MATLAB实现图像纹理特征提取：自相关函数法、灰度共生矩阵、分数阶傅里叶变换。GUI界面。运行后可自定义自相关函数的x和y轴偏移，灰度共生矩阵的距离和角度，分数阶傅里叶变换的阶数。输出相应的特征图。(MATLAB realize image texture feature extraction: autocorrelation function method, gray co-occurrence matrix, fractional Fourier transform. GUI interface. After operation, the X and Y axis shifts of the correlation function, the distance and the angle of the GLCM, and the order of the fractional Fu Liye transform can be defined. Output the corresponding feature map.)

这是用于人脸识别和人脸定位的主动形状模型（asm）matlab工具箱。推荐(This for face recognition and facial shape positioning initiative model (asm2) Matlab toolbox. Suggest)
