Watermark Selection for Light Field Rendering in FTV

The recent advances in Image Based Rendering (IBR) has pioneered a new technology, named Free-View Television (FTV), in which the viewers select freely the viewing position and angle of the transmitted multi-view video. In Free-View Television, a person might record a personal video of this arbitrarily selected view and misuse this content, therefore, it is apparent that copyright and copy protection problems exist and should be solved for free- view TV. Among many alternative rights management methods, the copyright problem for visual data is approached by means of embedding hidden imperceptible information, called watermark, into the image and video content. In this paper, we focus on this problem by proposing a simple watermarking scheme. The watermark should not only be resistant to common video processing and multi-view video processing operations, it should also be extracted from a generated video for an arbitrary view. Based on this remark, we evaluate the performance of several watermarks according to their ability to survive in the new generated arbitrary view.
