The recent advances in Image Based Rendering (IBR) has pioneered a new technology, free view point television, in which TV-viewers select freely the viewing position and angle by the application of IBR on the transmitted multi-view video. In this paper, exhaustive tests were carried out to conclude to the best possible watermarking for free-view television. 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.

Best watermarking selection for free-view point television Postofidis, EvIambios E.; Koz, Per; Triantafyllidis, Georgios (2007-06-30) The recent advances in Image Based Rendering (IBR) has pioneered a new technology, free view point television, in which TV-viewers select freely the viewing position and angle by the application of IBR on the transmitted multi-view video. In this paper, exhaustive tests were carried out to conclude to the best possible watermarking for free-view television.

Free-view watermarking for free-view television Koz, Alper; Cigla, Cevahir; Alatan, Abdullah Aydın (2006-10-11) The recent advances in Image Based Rendering (IBR) has pioneered a new technology, free-view television, in which TV-viewers select freely the viewing position and angle by the application of IBR on the transmitted multi-view video. Noting that the TV-viewer might also record a personal video for this arbitrarily selected view and misuse this content, it is apparent that copyright and copy protection problems also exist and should be solved for free-view TV. In this paper, we focus on this problem by propos...
WATERMARKING FOR IMAGE-BASED RENDERING VIA HOMOGRAPHY-BASED VIRTUAL CAMERA LOCATION ESTIMATION Koz, Alper; Cigla, Cevahir; Alatan, Abdullah Aydın (2008-10-15) The recent advances in Image Based Rendering (IBR) have pioneered freely determining the viewing position and angle in a scene from multi-view video. Noting that a person could also record a personal video for this arbitrarily selected view and misuse this content, apparently, copyright and copy protection problems also exist and should be solved for IBR applications. In our recent work [1], we have proposed a watermarking method, which embeds the watermark pattern into every frame of multi-view video and e...
WATERMARKING FOR DEPTH-IMAGE-BASED RENDERING Halici, Eren; Alatan, Abdullah Aydın (2009-11-10) In this paper, a novel watermarking method for depth-image-based rendering methods employed in free viewpoint television systems is proposed. The proposed method uses a correlation-based approach; where a watermark pattern is warped for each different view of the multi-view source video, and embedded to the texture maps of those views in spatial domain. First, the projection matrix of the 2D rendered image is estimated; then, using this matrix, a rendered watermark is formed by warping the original watermar...
A SPATIOTEMPORAL NO-REFERENCE VIDEO QUALITY ASSESSMENT MODEL Konuk, Baris; Zerman, Emin; NUR YILMAZ, GÖKÇE; Akar, Gözde (2013-09-18) Many researchers have been developing objective video quality assessment methods due to increasing demand for perceived video quality measurement results by end users to speed-up advancements of multimedia services. However, most of these methods are either Full-Reference (FR) metrics, which require the original video or Reduced-Reference (RR) metrics, which need some features extracted from the original video. No-Reference (NR) metrics, on the other hand, do not require any information about the original v...
