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,然后对这个变换后的图像进行IDCT,就会得到需要的水印图像。(While the carrier image digital watermarking algorithm based on DCT domain include watermark modulation, watermark embedding and watermark extraction, the first of the watermark embedded in a carrier modulated image before using Logistic chaotic sequence, only+1 and-1 to get a random sequence of watermark, Global DCT transform, then the watermark image is embedded most important part of the human visual system, i.e. the largest DCT coefficients, DC (Direct Current) in this section also contains the largest coefficient, the coefficient of this part of the human visual characteristics to meet, make watermarks Embed better performance. The watermark embedding algorithm is with these coefficients are multiplied to obtain new coefficients, and then a new factor to replace the original coefficients, namely discrete cosine domain to obtain an image watermarked and then transformed the image of this conduct IDCT, on watermark image will be needed.)
