各种数字水印的matlab源代码，DCT，小波变换等。(Various digital watermarking matlab source code, DCT, wavelet transform.)

提出了一种离散小波变换域实现图像水印的方法。这种算法充分利用小波变换的特点,把原始图像及水印图像塔式分解,在多分辨率分解后的相同的频段来嵌入水印信息。该方法也利用了人眼视觉特性,算法简单而有效。实验证明,该算法较好地解决了水印不可见性与鲁棒性之间的矛盾,对常见的水印攻击都有较强的鲁棒性。(presents a discrete wavelet transform domain image watermarking method. This algorithm using wavelet transform characteristics, the original image and the watermark image tower decomposition, Multiresolution decomposition in the same frequency band to the embedded watermark. The method has also been used HVS, the algorithm is simple and effective. Experiments show that the algorithm can solve the watermark is visible with the robust nature of, common to have more attacks watermark robustness.)

丰富的matlab指令!希望能对学习matlab的朋友提供一点帮助！(Matlab command rich! Want to be able to learn a little matlab help of friends!)

利用户相关进行图像配准，精度高，希望对读者有所帮助。(image registration with cross corr)

衰落信道仿真 function r = rayleigh( fd, fs, Ns ) r = rayleigh(fd,fs,N) A Rayleigh fading simulator based on Clarke s Model Creates a Rayleigh random process with PSD determined by the vehicle s speed. INPUTS: fd = doppler frequency set fd = v*cos(theta)/lambda v = velocity (meters per second) lambda = carrier wavelength (meters) theta = angle w/ respect to tangent (radians). fs = sample frequency (Samples per second) Ns = number of samples of the Rayleigh fading process to produce OUTPUTS: r = row vector containing Ns samples of the Rayleigh fading process Author: Matthew C.
