The idea is to integrate image-based FTV with photo-realistic views and model-based FTV with wide viewing zone. Surface-Based FTV has advantages of both types of FTV because it represents 3D scenes by surfaces and uses ray and surface information for view synthesis. Analyzing relation between ray and surface, a method to detect surfaces from parallel and perspective views in three directions.}, title = {[招待講演]Surface-Based FTVの提案}, year = {2021} }
