Watermarking scheme based on energy modulation for compressed video

A high capacity watermarking scheme with high computational efficiency was proposed based on modulating the energy of certain image regions. During the modification, the Watson´s perceptual model is employed to restrict the modified magnitude of coefficients. This scheme is capable of embedding 2640 bits of information in each frame with dimensions 704×480 pixels. Experimental results indicate the watermarks are robust to significant valumetric distortions (including additive noise, low-pass filtering, lossy compression and valumetric scaling).
