Abstract

This paper proposes a robust video watermarking for H.264/AVC using block polarity and AC correlation schemes. In the proposed method, the intra frames are used for watermarking embedding and protection. Block polarity is obtained using the nonzero quantized DC coefficient in each integer DCT block. Then, the selective block polarity of DCT block is used to perform the Intra prediction modes for luminance block. AC correlation is obtained by adjusting the relative between the AC coefficients of these DCT blocks. Finally, one watermark bit is embedded into each processed DCT block. Experimental results show that the proposed method is robust to the attacks of cropping, noise addition, brightness, wind effect, and cloud effect.
