Color image watermark algorithm based on SVD and lifting wavelet transformation
基于奇异值与提升小波的彩色图像水印算法

This paper proposed a color image digital watermarking algorithm based on SVD and LWT.At first transformed the color image to YUV spatial domain from RGB.Then transformed the luminance component Y of color image in YUV color space with the lifting wavelet,decomposed the coefficients of low frequency by SVD,similarly decomposed the watermark image by SVD and embedded in SVD of the coefficients of low frequency.The simulation results indicate that the algorithm has both good quality for watermarked image invi...
