WebNov 21, 2011 · We present new algorithms for creating and rendering visual hulls in real-time. Unlike voxel or sampled approaches, we compute an exact polyhedral … WebWe propose an exact method for efficiently and robustly computing the visual hull of an object from image contours. Unlike most existing approaches, ours computes an exact description of the visual hull polyhedron associated to polygonal image contours.
WebDec 1, 2011 · Franco and Boyer computed exact polyhedral visual hull by cutting and joining the visual rays casted from silhouettes and joining them together [3]. Liang and … Webet al. [10] distribute the visual hull computation among a cluster of PCs to achieve interactive recon-struction rates. The main drawbacks of voxel-based approaches are the large memory requirement and quantization artifacts.
