WebAbstract: This blind color image watermarking technique based on Hessenberg Decomposition and Schur Decomposition examines the performance in terms of invisibility and robustness. For the security purpose, the Fibonacci-Lucas Transform is used to scramble the watermark image. This technique is tested with several color images from … WebClicking the locations on each map reveals more information.
