The proposed method involves many techniques to conform a secure and robust watermarking. In the proposed technique the watermark is embedded in 3 rd level of DWT (Discrete Wavelet Transform) and before embedding the watermark image is passed through chaotic encryption process for its security, ...
Using these frames watermarked video is constructed. The extraction process reverses the embedding process without the original video. Compared with other watermarking approach, experimental result shows that the proposed method produces robust watermark against different types of attack. 展开 ...
However, the overlapping between local feature regions has not been resolved in this approach. Song et al. [30] proposed a novel image watermarking technique using a region-adaptive approach to further improve robustness. Watermark data is embedded on different regions of the host image using a ...

Third, there is a tradeoff between robustness and capacity, so robust watermarks cannot be long. In addition to this, the use of watermarking in cooperative architectures would imply an important cost in bandwidth and delays, since every time that a user embeds a watermark in an image, he/...
Thus a hybrid method is proposed using DCT and DWT. From table it can been seen that average PSNR of DCT watermarking is 58.90dB and that of DCT and DWT is 66.26 dB. Thus, proposed hybrid technique is more imperceptible and robust against variety of noise and filtering attacks like ...
