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 watermark pattern. Finally, Symmetric Phase Only Matched Filtering is used to find the correlation between the rendered image and the rendered watermark. Extended simulations with various attacks show the applicability of the proposed solution.

Watermarking tests for free-view point television
Apostolidis, Evlambios E.; Koz, Alper; Triantafyllidis, Georgios (2007-05-09)
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 gen...

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 3D represantations
Koz, Alper; Alatan, Abdullah Aydın; Department of Electrical and Electronics Engineering (2007)
In this thesis, a number of novel watermarking techniques for different 3D representations are presented. A novel watermarking method is proposed for the mono-view video, which might be interpreted as the basic implicit representation of 3D scenes. The proposed method solves the common flickering problem in the existing video watermarking schemes by means of adjusting the watermark strength with respect to temporal contrast thresholds of human visual system (HVS), which define the maximum invisible distorti...
Retraction Free Motion Approach and Its Application in Automated Robotic Edge Finishing and Inspection Processes
Nemer, Mahmoud; Konukseven, Erhan İlhan (null; 2016-12-15)
In this paper, a motion generation algorithm for a six Degrees of Freedom (DoF) robotic hand in a static environment is presented. The purpose of developing this method is to be used in the path generation of the end-effector for edge finishing and inspection processes by utilizing the CAD model of the considered workpiece. Nonetheless, the proposed algorithm may be extended to be applicable for other similar manufacturing processes. A software package programmed in the application programming interface (AP...
