Free-View TV watermark selection based on the distribution characteristics

Abstract

In Free-View Television (FTV), the user can interactively control the viewpoint and generate new arbitrary views of a dynamic scene from any 3D position. The new views might be recorded and misused. Therefore the problem of copyright and copy protection in FTV should be solved. Among many alternative rights management methods, the copyright problem for visual data can be approached by means of embedding hidden imperceptible information, called watermark, into the image and video content. But this approach differs from the simple watermarking technique, since watermark in FTV should not only be resistant to common video processing and multi-view video processing operations, it should also be easily extracted from a generated video of an arbitrary view. In this paper, we focus on the evaluation of the performance of several watermarks according to their distribution characteristics in order to survive in the new generated arbitrary views of FTV.
