Title: | Free Viewpoint Video for Soccer using Histogram-Based Validity Maps in Plane Sweeping | Authors: | GOORTS, Patrik MAESEN, Steven DUMONT, Maarten ROGMANS, Sammy BEKAERT, Philippe |
Issue Date: | 2014 | Publisher: | SciTePress | Source: | Proceedings of The International Conference on Computer Vision Theory and Applications (VISAPP), p. 378-386 | Series/Report: | INSTICC Conference Proceedings | Abstract: | In this paper, we present a method to accomplish free viewpoint video for soccer scenes. This will allow the rendering of a virtual camera, such as a virtual rail camera, or a camera moving around a frozen scene. We use 7 static cameras in a wide baseline setup (10 meters apart from each other). After debayering and segmentation, a crude depth map is created using a plane sweep approach. Next, this depth map is filtered and used in a second, depth-selective plane sweep by creating validity maps per depth. The complete method employs NVIDIA CUDA and traditional GPU shaders, resulting in a fast and scalable solution. The results, using real images, show the effective removal of artifacts, yielding high quality images for a virtual camera. | Keywords: | sports broadcasting; view interpolation; plane sweep; virtual viewpoint; validity maps; GPU; CUDA | Document URI: | http://hdl.handle.net/1942/17016 | ISBN: | 9789897581335 | ISI #: | 000412740600046 | Category: | C1 | Type: | Proceedings Paper | Validations: | ecoom 2019 |
