Description
Summary:In this paper, an object-based robust video watermarking scheme against geometric attacks is proposed. The synchronization problem can be solved by object normalization. The video object is firstly extracted, normalized and transformed into its discrete wavelet domain. A binary logo watermark is embedded into the lower frequency subband of the DWT domain by adjusting the relation between the selected coefficient pairs. The theoretical analysis and experimental results show good robustness of proposed scheme against object manipulations and some affine transforms.
