To realize this concept, many conventional methods have been proposed. However, these methods require high computational cost to synthesize a virtual viewpoint because they have to calculate huge data to express three-dimensional information. To overcome this problem, we propose a simple and fast free viewpoint synthesis method based on a visual hull, which is a general concept in this field. We calculate the silhouette of an object along view-dependent planes in virtual space by simple projection from images to the 3D space, and express the whole shape of the object by integrating the planes. This scheme works very quickly while providing fine quality because it consists of standard functions in general GPU architecture. The experimental results show our method can generate a fine virtual view of an object by using multiple videos in real time.","subitem_description_type":"Other"}]},"item_4_description_8":{"attribute_name":"論文抄録(英)","attribute_value_mlt":[{"subitem_description":"Free viewpoint technologies that synthesize virtual viewpoint by using multiple actual videos would provide immersive experiences for users.
