msequence.m
- m序列生成,可用于图象,音频置乱,如用于数字水印中可去除图象间的相关性
LFSR
- 基于LFSR生成m序列的图像隐藏算法,利用线性插值的方法将经过异或的的图像隐藏在同样大小的一幅载体图像中-Based on LFSR generates m-series images hiding algorithm, using linear interpolation method will be through the exclusive or of the hidden images of the same size of a vector image
Algorithm-of-colour-image-watermark
- 据扩频通信技术原理,利用m序列生成水印,通过扩频码与待检测载体图像的相关性设计了DCT域 的彩色图像水印算法-Abstract:An algorithm of colour image watermark in DCT domain based on spread spectrum communication was introduced
m
- matlab生成伪随机序列,可以便于仿真实验,以及图像研究。-matlab generate pseudo-random sequence, can facilitate the simulation experiments, as well as image research
henon
- 基于henon映射的加密程序。首先生成混沌序列,利用henon映射生成两个长度为(M*N)/2的序列。其次,将混沌序列置乱。最后,异或运算:将初始图像进行排序变换,做异或运算,从而实现对初始图像的置乱加密,得到最终的加密图像。-Based henon mapping encryption programs. First generate chaotic sequence, using henon mapping generates two length (M* N) sequence/2. Se
