一种嵌入三维动画特效参数的数字水印算法

三维动画因其高信息量和高逼真性,广泛应用于虚拟展示、动画电影等领域。为了有效保护三维动画的知识产权,提出一种嵌入三维动画特效参数的数字水印算法。将三维动画中粒子效果和动力学效果等特效参数作为水印嵌入载体,结合满秩分解、奇异值分解和三角分解,将水印信息高效地嵌入到特效参数组成的矩阵中。由于水印是嵌入在特效参数而非场景主要特征中,所以水印具有很好的透明性。实验结果表明,该算法复杂度较低且鲁棒性较高,具有很好的推广性。

A DIGITAL WATERMARKING ALGORITHM FOR EMBEDDING 3D ANIMATION SPECIAL EFFECT PARAMETERS

Due to its high information content and high fidelity,3D animation is widely used in virtual display,animation film and other fields.To effectively protect the intellectual property of 3D animation,this paper proposes a digital watermarking algorithm for embedding 3D animation special effect parameters.The particle effect,dynamic effect and other special effect parameters in 3D animation were taken as the watermark embedding carrier.Combined with full rank decomposition,singular value decomposition and triangular decomposition,the watermark information was efficiently embedded into the matrix composed of special effect parameters.Because the watermark was embedded in the special effect parameters rather than the main character of the scene,the watermark had good transparency.The experimental data show that the algorithm has low complexity and high robustness,and it has good generalization.
