    Three-dimensional scene representations: modeling, animation, and rendering techniques
    (Springer, 2008) Güdükbay, Uğur; Durupınar, Funda; Özaktaş, Haldun M.; Onural, Levent
    Modeling the behavior and appearance of captured three-dimensional (3D) objects is a fundamental requirement for scene representation in a three-dimensional television (3DTV) framework. By using the data acquired from multiple cameras, it is possible to model a scene with high quality visual results. In fact, 3D scene capturing and representation phases are highly correlated. Information acquired from the capturing phase can be employed in the representation phase by using computer graphics and image processing techniques. The resultant model then allows the users to interact with the scene, not just remain observers but be participants themselves. Thus, the main considerations for the quality of a scene representation technique are basically the accuracy of the technique about how the results correspond to the original scene and the efficiency of the technique as real-time performance is required.
