Abstract :
In this paper, a genetic algorithm (GA) based video watermarking scheme in the discrete wavelet transform (DWT) domain is proposed. Scene change analysis is first conducted to decompose video into different scenes. Each frame of the video is transformed to wavelet domain by DWT. The watermark image is decomposed into 8-bit planes, scrambled and embedded into the mid-frequency DWT coefficients. The quality of the watermarked video is enhanced by GA. Experimental results demonstrate that it is robust to common attacks in video watermarking such as frame dropping, frame averaging additive noise and lossy compression
