3D MAX动画中材质参数的数字水印算法
Digital watermarking algorithm of texture parameters in 3D MAX animation
摘要
Abstract
In order to protect the copyright of the multimedia digital resources,a digital watermarking scheme for 3D MAX animation is put forward,and the texture parameters in animation are selected as the positions of watermark embedding. A ma-trix composed of several effective texture parameters is performed with wavelet transform to get the approximation component and detail component,then the watermark information is decomposed with PCA to get the first component,and the approximation component and first component are conducted with data fusion. The wavelet inverse transform is carried out for the approximation component and original detail component to embed the watermarking into a new matrix of texture parameters. The elements in the new matrix is used to reset the texture to obtain the 3D animation with embedding watermark. The experimental results show that the algorithm has simple operation,good watermark concealment,strong attack resistance and perfect extensibility.关键词
