| dc.description.abstract | This paper describes a technique used to approximate the surface of an object’s visual hull. The hull’s basic structure is initially represented by a partitioned 3D space using voxels. The marching cubes algorithm then assigns polygonal patches to surface voxels depending on a certain criteria. It is less computationally intensive to manipulate a few triangular patches than a number of six-faced voxels. The visual hull model is further refined by applying a binary search to the vertices of each surface that improves the positional accuracy of each vertex. The method is applied to a small plastic cat using a 5-camera system and results are shown. | |
