image_processing

说明：  本代码实现了K均值聚类，代码简单易懂，容易初学者学习(This code realizes K-means clustering, the code is easy to understand, easy for beginners to learn)

JSteg隐写技术matlab实现代码--基本思想：用秘密信息比特直接替换JPEG图像中量化后DCT系数的最低比特位，但若量化后DCT系数为0或者1，则不进行处理。（DCT系数的LSB嵌入） (JSteg steganography matlab code- the basic idea: direct replacement with the secret information bits JPEG image quantized DCT coefficients in the least significant bit, but if the quantized DCT coefficient is 0 or 1, no processing. (DCT coefficients LSB embedding))

主要是一些经典的视觉跟踪算法的MATLAB代码，tracker包括CREST,CSK,CT,ECO,KCF,LOT,SCM和Struck。(Visual object tracking,include CREST,CSK,CT,ECO,KCF,LOT,SCM and Struck.)

自己写的形态学的寻找连通域的实现方法。调用了自己写的腐蚀和膨胀函数(Morphological write their own search for the realization of methods connected domain. Call to write their own corrosion and expansion function)

此程序为VC++常用数值算法这本书附赠的光盘中包含了本书中全部的源代码()

视频读取并提取目标背景 背景要求是静止的 效果很好(Video read and extract the target background static background requirements are well)

对可见光图片的人脸活体判断，内有C++和matlab实现，具体说明详见readme(For the visible light picture of the human face to determine, there are C++ and matlab implementation, specific instructions see readme)
