文简要介绍了指纹识别的基本步骤，分别是指纹图像预处理、指纹特征提取、指纹匹配(This paper briefly introduces the basic steps of fingerprint recognition, which are fingerprint image preprocessing, fingerprint feature extraction and fingerprint matching)

图像椒盐噪声去除研究程序，在matlab条件下编译的，主要应用中值滤波法对噪声的去除．(Impulse Noise Removal procedures, the conditions under Matlab Compiler. Application of the main method of filtering noise removal.)

來自於2012年IEEE TIP的論文 Efficient Contrast Enhancement Using Adaptive Gamma Correction With Weighting Distribution ，其功能為透過分析影像中的直方圖統計資訊，達到快速增強影像對比的結果。(From the 2012 IEEE TIP paper "Efficient Contrast Enhancement Using Adaptive Gamma Correction With Weighting Distribution"which functions as a histogram of the image by analyzing statistical information, to quickly enhance image contrast.)

根据16点DFT算法得出的运算流程图，得到的16点DFT蝶形运算函数(16 point s DFT algorithm)

一个选择模板的匹配方式，附带视觉标定,可以自由的选择模板进行匹配(A matching pattern of selected templates with visual calibration)

用hilbert曲线扫描图像后，进行图像检索的代码，里面有很多有用的代码(After scanning the image with the hilbert curve, the image retrieval code, there are a lot of useful code)

2012 CVPR 文章：Segmentation Using Superpixels A Bipartite Graph Partitioning Approach对应的代码(2012 CVPR paper：Segmentation Using Superpixels A Bipartite Graph Partitioning Approach)

利用多尺度高斯函数去除场景的光照分量；然后构造了一种二维伽马函数，利用光照分量的分布特性调整二维伽马函数的参数，降低光照过强区域的亮度值，提高光照过暗区域的亮度值，最终实现对光照不均匀图像的自适应校正处理。(The multi scale Gauss function is used to remove the illumination component of the scene, and then a two-dimensional gamma function is constructed. The parameters of the two-dimensional gamma function are adjusted by the distribution characteristics of the illumination component, the brightness value of the light illuminated region is reduced and the brightness value of the light dark area is improved. Finally, the adaptive correction of the uneven illumination image is realized. Positive treatment.)

利用MATLAB编程实现车牌号识别并显示，并对出入库时的车辆时间进行记录，计算车辆在停车场的时间(The license plate number is identified and displayed by MATLAB programming, and the vehicle time is recorded and the time of vehicle in the parking lot is calculated.)
