Video Watermarking Algorithm Based on Relative Relationship of DCT Coefficients
نویسندگان
چکیده
A video watermarking algorithm based on relative relationship of DCT coefficients is proposed in this paper. By modification of coefficients on chosen positions, the robustness of watermark embedding is ensured. Meanwhile, as the relationship of coefficients remains unchanged, the quality of video is not affected. The analysis results shows that the performance of proposed algorithm is better than the typical algorithms.

متن کاملA chaos-based video watermarking algorithm
The intriguing characteristics of chaotic maps have prompted researchers to use these sequences in watermarking systems to good effect. In this paper we aim to use a tent map to encrypt the binary logo to achieve a like-noise signal. This approach makes extraction of the watermark signal by potential attacker very hard. Embedding locations are selected based on certain principles. Experimental ...

The present paper is intended to present a robust multiplicative video watermarking scheme. In this regard, the video signal is segmented into 3-D blocks like cubes, and then, the 3-D wavelet transform is applied to each block. The low frequency components of the wavelet coefficients are then used for data embedding to make the process robust against both malicious and unintentional attacks. Th...

In this paper, we propose an effective watermarking algorithm based on a pseudo 3D DCT and quantization index modulation for vide against the attacks. The watermark is principally inserted into the uncompressed domain by adjusting the correlation between DCT coefficients of the selected blocks, and the extraction of watermark is blind. This approach includes a pseudo 3D DCT, watermark embedding...
