This paper presents a novel depth map generation method based on geometric information. Our method divides a 2d image into two parts—the foreground and the background. Through extracting the predominant lines and vanishing point of the background, the background depth map is determined. Then we use this depth map as a ‘scalar’ to measure the depth value of the foreground object. Finally, the depth...
A novel watermarking method using singular value decomposition (SVD) is presented in this paper. In this algorithm, a 3D model is taken as a model that consists of triangular meshes, and we select some triangles called independent triangles set (ITS) to generate a Hankel matrix and apply SVD on it, then watermarks are embedded through modulating singular values. The watermarks that embedded by this...
