数字信号误码率和信噪比的matlab程序（m file）包括单极性方波加性包噪声，接受检测电平判决、误码率、信噪比(Digital signal bit error rate and signal to noise ratio of the matlab program (m file) of packages, including unipolar square Microwave and noise level being tested sentence error rate, signal to noise ratio)

TVDENOISE Total variation grayscale and color image denoising

the folder gives information about the image forgery detection. detection is made by examining the sift and ransac features of the image. color processing is done as a preprocessing step.

ldpc编码，随机生成H矩阵，LLR-BP算法译码，有我详细的注解，非常详尽(ldpc coding, randomly generated H matrix, LLR-BP decoding algorithm, with my detailed notes, very detailed)

用MATLAB编写的 LSB 信息隐藏软件(MATLAB LSB prepared by the Software Information Hiding)

Feigenbaum this is development of matlab

用于相机标定的两种经典算法的源程序：张正友法和Tasi法(Used for camera calibration source of the two classical algorithms: Zhang Zheng-you Law and Tasi France)

该代码主要是解决激发介质问题，用来计算每一个元胞。(The code is mainly to solve the problem excitable media, used to calculate each cell.)

多个脉冲积累后可以有效地提高信噪比，中频积累时要求信号间有严格的相位关系，即信号时相参的，所以称为相参积累。(Multiple pulse accumulation can effectively improve SNR, if integration requires strict phase relationship between signals, whereby the signal coherent, so called coherent accumulation.)
