2020/11/23 · This paper presents a quaternary watermarking of color image using Schur decomposition. The superiorities of the presented scheme contains three points.

Secondly, the algorithm uses affine transform that have high security to encrypt the location of the color watermark pixels, which improves the security of the ...
