- 基于LFSR和混沌理论的伪随机序列生成方法 -Pseudo-random sequences generating method based on LFSR and chaos theory
DCT
- 基于DCT域的数字水印算法主要包括水印调制、水印嵌入和水印提取,首先在嵌入载体图像之前用Logistic混沌序列对水印进行调制,得到一个只有+1和-1随机序列的水印,同时将载体图像进行全局DCT变换,然后将水印图像嵌入人类视觉系统最重要的部分,即DCT最大的系数,DC(Direct Current)部分也包含在这最大的系数中,这部分的系数满足人类视觉特性,会使水印嵌入的性能更好。嵌入算法是将水印与这些系数进行相乘获得新的系数,再用新的系数来替换原来的系数,即获得嵌入水印后的离散余弦域的图像,然后
