在頻率域嵌入水印信息,是目前一種主流的嵌入算法,在很多文獻中,都是通過量化音頻信號的ftf系數, dct系數,或者是dwt域的高頻系數。我們認為:在小波域內的近似分量(低頻系數)中嵌入水印能夠提高數字水印的魯棒性,通過量化嵌入水印的方法,將水印嵌入到近似分量中每個分段中最大值上,因為這樣對于同一個量化步長,量化對象的幅值越大,所疊加的“噪聲”就越小,從而提高了數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
