Paper Abstract

This paper presents a scheme that apply the pixel-wise masking technique used in image watermarking into video sequence. The proposed algorithm deploys the video watermarking in the redundant discrete wavelet transform (RDWT) domain. The advantages of using an overcompleted wavelet transform instead of the traditional critically subsampled discrete wavelet transform (DWT) are discussed. The redundancy in the transform domain facilitates a better detection of the video texture characteristics in a video sequence. Thus leads to an efficient watermark casting scheme, in which more strength of watermark can be embedded into the video sequence, but still not perceivable. Different methods of using RDWT or DWT coefficients to add the watermarking are compared. Experimental results show that RDWT domain video watermarking offers greater robustness than DWT domain method.
