synchronization between the color channels, a new quaternion Schur (QSchur) decomposition algorithm is presented in this paper …-preserving algorithm is used to reduce the running time of the proposed algorithm. Simulation experiments and analysis demonstrate that … this algorithm has stronger robustness and higher security when the actual embedding rate and invisibility are the same as …
