A Scene Based Video Watermarking in Discrete Multiwavelet Domain

چکیده
The rapid increase in internet usage has resulted in the media ownership and attention towards intellectual property rights among internet users. In this paper, a Discrete Multiwavelet Transform (DMWT) and Quantization Index Modulation (QIM) based video watermarking is proposed. A logo watermark is inserted in the uncompressed domain of a video. Using QIM, the watermark is embedded into the selected multiwavelet coefficients by quantizing the coefficients. Scrambled watermarks are generated using a set of secret keys, and each watermark is embedded in each motionless scene of the video. The watermark extraction does not require the original video. Experimental results demonstrate that the proposed method is robust against the frame dropping, averaging, swapping, and statistical analysis attacks. It is also robust against some intentional and unintentional attacks. Keywords— Discrete Multiwavelet Transform, Quantization Index Modulation, Quantization Step, Scene-Change and S-Transform

متن کاملA Modified Digital Image Watermarking Scheme Based on Nonnegative Matrix Factorization
This paper presents a modified digital image watermarking method based on nonnegative matrix factorization. Firstly, host image is factorized to the product of three nonnegative matrices. Then, the centric matrix is transferred to discrete cosine transform domain. Watermark is embedded in low frequency band of this matrix and next, the reverse of the transform is computed. Finally, watermarked ...
