| Outline of Final Research Achievements |
Several fundamental devices and methods were developed for a video-based computer graphics technique to synthesize a free-viewpoint video from multiple videos to allow a free-viewpoint to move in a wide range. Two types of devices, which were named camera clusters, were developed: one has a one-dimensional whole circumference arrangement of cameras to generate panorama videos; and another has a two-dimensional array arrangement of cameras to generate free-viewpoint videos. To use multiple camera clusters to generate free-viewpoint videos in a wide range, a view morphing-based method, a plane sweep-based method, and a method combining volume intersection and texture synthesis were developed.
