- W2364468761 abstract "Aimed at the insecurity of the digital products,one digital watermarking technique for color image was proposed,utilizing the speediness of two-dimensional discrete wavelet transforms that map integers to integers and combining characteristic of the human's optical system.Firstly,color image is converted from RGB space to YUV space and multilevel discrete integer wavelet transform was done to the Y frequency.Secondly,a meaning character string or binary image as a watermark is embedded into the low frequency part of the carrier image.This system chooses the appropriate position to embed the watermarking.The experimental results indicate that the system not only enables the watermarking to have the very good invisibility,but also makes the watermarking have very strong robustness to the general image attacks,such as noise,filter,rotation,compression and so on.The watermark technique has a strong practicability,little impress to the original carrier image,can resist JPEG compression." @default.
