Abstract :
In this paper, we analyze typical singular value watermarking algorithm based on singular value decomposition (SVD) and point out an error in the embedding algorithm. After corrected this error, we optimize interval range used in embedding algorithm. Experimental results demonstrate the algorithm analysis that under same quantization step, using this optimal embedding algorithm will get better peak signal to noise ratio (PSNR) than preview algorithms.
