| Abstract(in English) | In this paper, we propose a robust method of extracting precisely identified textures of multiple objects among multi-view cameras and consecutive frames for rendering an immersive free-viewpoint video in a large outdoor space such as a soccer stadium. For a free viewpoint video that provides viewers with an immersive experience, each object has to be identified consistently among all cameras for every frame to share textures of the same objects and replace them when an occlusion occurs. In order to achieve the above requirement, the proposed method extracts objects' silhouette regions and tracks each identified object by associating a tracking ID and a closed silhouette region for every camera. As the frame by frame process, the method checks whether or not occlusion occurs for each tracking region, and modifies the texture region by projecting the world coordinate of the object in SD-space, which is estimated in another non-occluded camera if it occurs. Experimental results revealed that the proposed method successfully extracted identified textures of multiple objects and improved the robustness for occlusions compared to the conventional method. Furthermore, it was also confirmed that the free-viewpoint video was rendered precisely with the proposed approach since the occluded regions were successfully reconstructed. |
