Animation Zero Watermarking Algorithm Based on Edge Feature

Based on Edge Feature Animation zero watermarking algorithm, by making full use of the features and characteristics of the carrier itself, the zero watermarking technology get its own advantages to achieve the best effect of copyright protection. This paper proposes a digital video watermarking scheme based on 2D-DWT and pseudo 3D-DCT transformation, otherwise Singular Value Decomposition are applied. In order to enhance the robustness of watermark, the contour wave transform with good multi-scale and multi-direction analysis is used to transform the original vector. During the embedding process, the Visual cryptography and Chaotic scrambling are used in order to enhance the security of the algorithm. The method selects some key-frames in raw video to extract the luminance components and take them into some groups. The experiments are conducted to verify the robustness for some common signal processing and framework-based attacks.
