Lotfi Abdi, Faten Ben Abdallah, Aref Meddeb · 2015
In this paper, a low complexity video watermarking scheme for H.264 has been presented. Our contribution is to attain lower complexity in embedding procedure and extracting watermark. At the same time, we avoid a bit-rate increase and improve the runtime-efficiency and embedding capacity without sacrificing quality. The watermark is embedded into a video sequence by modifying the number of nonzero-quantized AC coefficients in a 4x4 block of I frames. The experimental results show that the proposed method can prevent a bit-rate increase and improve the runtime-efficiency and embedding capacity without sacrificing the perceptual quality.
