WATERMARKING FOR 3D REPRESENTATIONS (2007)
Abstract / truncated to 115 words
In this thesis, a number of novel watermarking techniques for different 3D representations are presented. A novel watermarking method is proposed for the mono-view video, which might be interpreted as the basic implicit representation of 3D scenes. The proposed method solves the common flickering problem in the existing video watermarking schemes by means of adjusting the watermark strength with respect to temporal contrast thresholds of human visual system (HVS), which define the maximum invisible distortions in the temporal direction. The experimental results indicate that the proposed method gives better results in both objective and subjective measures, compared to some recognized methods in the literature. The watermarking techniques for the geometry and image based representations of ... toggle 7 keywordsvideo watermarking – temporal contrast thresholds – 3d watermarking – geometry watermarking – free view watermarking – human visual system – projective invariants
