数字水印技术攻击试验，实现噪声、滤波、剪切、压缩、旋转攻击(Digital Watermarking attack test, realize noise, filtering, shear, compression, rotation attack)

TBD，检测前跟踪算法的仿真程序，比较多的文件，自己区分(TBD, tracking algorithm pre-test simulation procedures, a relatively large number of documents, to distinguish between their own)

比较简单的jpeg编码解码程序.( Compared with simple jpeg code decoding procedure )

Richardson-lucy去噪算法，泊松去噪(image denoising use Richardson lucy algorithm)

数字图像处理 小波处理 ，去噪音，比基于傅里叶变换的去噪方法好。 含噪信号经过预处理，然后利用小波变换把信号分解到各尺度中，在每一尺度下把属于噪声的小波系数去掉，保留并增强属于信号的小波系数，最后再经过小波逆变换恢复检测信号。(The noisy signal is pre-processed, then the signal is decomposed into different scales by wavelet transform. The wavelet coefficients belonging to noise are removed at each scale, and the wavelet coefficients belonging to the signal are retained and enhanced. Finally, the detected signal is restored by inverse wavelet transform. It is better than the denoising method based on Fourier transform.)

说明：  lsb数字水印算法，SB算法利用了数字图像处理中位平面的原理,即改变图像的最低位的信息,对图像信息产生的影响非常小,人眼的视觉感知系统往往不能察觉。以一幅256灰度的图像为例, 256 灰度共需要8 个位来表示,但其中每一个位的作用是不一样的,越高位对图像的影响越大,反之越低的位影响越小,甚至不能感知。(Digital watermarking algorithm based on lsb)

说明：  使用matlab对人体运动进行的简单的目标跟踪，使用卡尔曼滤波(Using matlab to human movement of the simple target tracking, the use of Kalman filter)

Haclon的源码，适用于金属表面的划痕检测(Haclon source code, suitable for metal surface scratch detection)

本系统实现指纹的识别和差异比对，通过差值程度来反映相似程度。(The system realizes fingerprint identification and difference alignment, and reflects the similarity degree by the degree of difference.)

说明：  窗口界面使用KAYA SDK连接采集卡相机获取采集图像(use KAYA sdk connect with grabber and capture image data)
