Title: | Augmented panoramic video | Authors: | HERMANS, Chris VANAKEN, Cedric MERTENS, Tom VAN REETH, Frank BEKAERT, Philippe |
Issue Date: | 2008 | Publisher: | BLACKWELL PUBLISHING | Source: | COMPUTER GRAPHICS FORUM, 27(2). p. 281-290 | Abstract: | Many video sequences consist of a locally dynamic background containing moving foreground subjects. In this paper we propose a novel way of re-displaying these sequences, by giving the user control over a virtual camera frame. Based on video mosaicing, we first compute a static high quality background panorama. After segmenting and removing the foreground subjects from the original video, the remaining elements are merged into a dynamic background panorama, which seamlessly extends the original video footage. We then re-display this augmented video by warping and cropping the panorama. The virtual camera can have an enlarged field-of-view and a controlled camera motion. Our technique is able to process videos with complex camera motions, reconstructing high quality panoramas without parallax artefacts, visible seams or blurring, while retaining repetitive dynamic elements. | Notes: | Univ Limburg, Hasselt Univ, Sch Informat Technol, Expertise Ctr Digital Media Transnat, B-3590 Diepenbeek, Belgium. | Document URI: | http://hdl.handle.net/1942/8299 | ISSN: | 0167-7055 | e-ISSN: | 1467-8659 | DOI: | 10.1111/j.1467-8659.2008.01125.x | ISI #: | 000255285500017 | Category: | A1 | Type: | Journal Contribution | Validations: | ecoom 2009 |
