ABSTRACT
The protection of intellectual property rights became recently a pressing need especially with the rapid growth of transmission techniques. In this paper, we present a mathematical model of a copyright protection method a blind video scene segmentation and 3D wavelet transform according to scene change. Mathematical model will be easier way to explain any sort of problem for research point of view first gray scale image as copyright sign is decomposed with different resolution of the decomposed video. As the multiresolution of the video is for spatial axis of the video. The experimental results show that this technique has more visually recognizable information of copyright ownership. In addition, these results proved its robustness against several video degradations and watermarking attacks including frame dropping, frame averaging and glossy compression.
