This paper considers the problem of interactively finding the cutting contour to extract components from an existing mesh. First, we propose a constrained random walks algorithm that can add constraints to the random walks procedure and thus allows for a variety of intuitive user inputs. Second, we design an optimization process that uses the shortest graph path to derive a nice cut contour. Then...
Most of the previous multi-view reconstruction algorithms focus on minimizing reconstruction distortion, i.e. reconstructing a 3D model as close to the real object as possible, and rely on subsequent simplification process to control the reconstruction rate for practical usage. In this paper, in addition to reconstruction distortion, we directly consider the reconstruction rate in wide-baseline multi-view...
For network-based graphics applications, a key challenge is how to efficiently transmit complex three-dimensional (3D) models over bandwidth-limited communication channels such as wireless links. Most existing 3D mesh coding algorithms do not consider the view-dependent rendering issue, and therefore result in transmitting unnecessary portions of 3D mesh models which leads to the waste in precious...
