在频率域嵌入水印信息,是目前一种主流的嵌入算法,在很多文献中,都是通过量化音频信号的ftf系数, dct系数,或者是dwt域的高频系数。我们认为:在小波域内的近似分量(低频系数)中嵌入水印能够提高数字水印的鲁棒性,通过量化嵌入水印的方法,将水印嵌入到近似分量中每个分段中最大值上,因为这样对于同一个量化步长,量化对象的幅值越大,所叠加的“噪声”就越小,从而提高了数字水印的不可感知性。 - Secondly , based on the shortage of full - image histogram , this thesis presents block histogram algorithm . thirdly , we study the image retrieval algorithm of color pair , and make the retrieval image having color similarity in space . finally , we apply hsv color - space corresponding to human visual characteristics to image retrieval , make use of human feeling on color to quantify the color weight , and analyze the two quantization methods
