A New Approach for Image Watermarking by using Particle Swarm Optimization
Ehsan Vahedi, Caro Lucas, Reza Aghaeizade Zoroofi, Mohsen Shiva · 2007
In this paper, the authors propose a new procedure for copyright protection by using a bio-inspired wavelet based data hiding approach. The proposed method takes advantage of human visual system (HVS) characteristics to provide better watermarked image quality. It also exploits visual secret sharing (VSS) technique to guarantee the security of the procedure. Performance improvement with respect to the existing algorithms is obtained by particle swarm optimization (PSO).
