A Blind Watermarking Model of the 3D Object and the Polygonal Mesh Objects for Securing Copyright
In this paper, we propose a novel model for 3D object watermarking. The proposed method is based on the properties of the discrete cosine transform (DCT) of the 3D object vertices to embed a secret grayscale image three times. The watermarking process takes place by using the vertices coefficients a...
