- W2356562923 abstract "A blind watermarking algorithm based on pseudo-random modulation technique in the mixed-domain for color images is proposed , First color image is converted from RGB space to HSI space, and the saturation component S is got , then the S-component after multi-wavelet transform generate some mid-frequency regions, then apply block DCT transform on the regions, at last pick out some midfrequency coefficients for each DCT sub-block according to a certain program.Generate two unrelated pseudo-random series with keys, with which modulation the DCT coefficients selected in the front to embed watermark..The Watermark is extracted through comparing correlation coefficient between the coefficients to be detected and each pseudo-random series, which do not need the original image.Experimental results show that the algorithm can resist shear, JPEG compression, zoom and greater intensity noise attack and so on effectively." @default.
