3D Copyright Protection Based on Binarized Computational Ghost Imaging Encryption and Cellular Automata Transform
In this paper, a watermark embedding scheme based on ghost image encryption and cellular automata transformation is proposed. In this scheme, the watermark forms speckle through different light intensities into a key, and the cellular automata transformation algorithm is embedded into the 3D image....
