- W2373870596 abstract "The paper proposes a blind watermarking algorithm based on NSCT and dither quantization.First,it transforms the image with NSCT and decomposes it with SVD block.Then,it sets the original watermark information chaos chaotically in order to eliminate the linear correlation.Subsequently,it alters every SVD block's singular value based on the dither quantization to embed the watermark.The results show that this blind watermarking algorithm has a good imperceptibility and strong robustness,and can well achieve a blind watermark extraction." @default.
