用C语言实现的离散傅里叶变换（DFT）的经典算法！比较实用！(C language classic of the discrete Fourier transform (DFT) algorithm! More practical!)

处理Gamma乘性噪声的PPB方法，考虑了非局部patch的相似性，可处理SAR图像去噪。(The PPB method for multicative noise removal, which based on the Probabilistic Patch similarity.)

说明：  基于LK的光流场计算以及跟踪，自己编的。(The calculation and tracking techniques based on Lucas-Kanade method.)

说明：  可自选输入和参数的中值/均值/拉伸滤波，各项参数说明详见.m文件注释(Median/Average/Linear Stretch Filter)

说明：  用FCM算法实现图像分割(图像源可以是灰度、索引和RGB图像)(FCM image segmentation algorithm (image source can be gray, indexes and RGB images))

：数字水印将感觉不到的信号嵌入到声频、视频和图像中以实现不同的目的。例如: 添加标题和版权保护。首先介绍 了有关数字水印的基本原理、重要属性及其主体框架。然后,将数字水印按不同角度划分为不同种类。讨论了各种各样的数 字水印算法以及数字水印在不同领域的应用,并简要介绍了对数字水印的攻击。最后,给出了数字水印当前的研究现状和发 展形式及前景。(: Digital watermark embedding imperceptible signals to the audio, video and images to achieve different purposes. Example: Add a title and copyright protection. Firstly, the basic principle about digital watermarking, and the main framework of the important attributes. Then, the digital watermark according to different angles into different types. Discussed a wide range of digital watermarking algorithms and digital watermarking applications in different fields, and a brief introduction of the digital watermarking attacks. Finally, the digital watermark of the current situation and development in the form of research and prospects.)

实现图像自动拼接和匹配，是毕业设计的作品，看看一定会对你有所帮助的！(Automatic image stitching and matching to achieve is a graduate design work, will you take a look at some helpful!)

包含实验图片，实验代码,对于从事数字图像处理工作有一定帮助(including experimental images and agrithms.It is benificial to image procecing workers.)

该程序包中有基于Hough变换的车道线检测，还有卡尔曼跟踪和别的小程序，都是可运行的，读者可自行学习(The package, the lane detection based on Hough transform, Kalman tracking and other small programs are running, readers can learn on their own)

pca 主成分分析c 代码和原理文档。。。。(PCA principal component analysis c code and principle document.)
