- W2365737390 abstract "A new watermarking method using computer generated holograms as the watermarks based on jointing discrete wavelet transform(DWT) and discrete cosine transform(DCT) for color images is proposed.The mark holograms are superposed on the DWT domain of the B channel of the host images.DCT is applied to remove correlation between DWT coefficients.Experimental results indicate that the presented scheme provides good robustness to withstand the wide variety of image processing attacks including JPEG compression,filtering,noise addition and cropping, etc.,and the watermark can be correctly extracted and reconstructed." @default.
