In this paper, we introduce a robust watermarking for the AVS video standard of China. The proposed algorithm is based on the Particle Swarm Optimization (PSO) technique. It is implemented in the compressed domain by modifying the quantized coefficients. The watermark signal is embedded in luminance components, whose embedding positions are optimized using PSO, resisting common signal processing operations...
In this paper, we propose a robust dual watermarking algorithm for video based on the audio video coding standard (AVS). One watermark is embedded in luminance components, whose embedding positions are optimized using the particle swarm optimization (PSO) technique, resisting common signal processing operations such as median filtering, adding noises, cropping and so on. To combat geometric and re-encoding...
