By a News Reporter-Staff News Editor at Journal of Technology -- Fresh data on Multimedia are presented in a new report. According to news reporting originating in Lausanne, Switzerland, by VerticalNews journalists, research stated, "Multiview video with interactive 2D look around at the receiver is a challenging application with several issues in terms of effective use of storage and bandwidth resources, reactivity of the system, quality of the viewing experience and system complexity. The impression of 3D immersion is highly dependent on the smoothness of the navigation and thus on the number of 2D viewpoints."
The news reporters obtained a quote from the research from the Institute of Electrical Engineering, "The classical decoding system for generating virtual views first projects a reference or encoded frame to a given viewpoint and then fills in the holes due to potential occlusions. This last step still constitutes a complex operation with specific software or hardware at the receiver and requires a certain quantity of information from the neighboring frames for ensuring consistency between the virtual images. In this work we propose a new approach that shifts most of the burden due to interactivity from the decoder to the encoder, by anticipating the navigation of the decoder and sending auxiliary information that guarantees temporal and interview consistency. This leads to an additional cost in terms of transmission rate and storage, which we minimize by using optimization techniques based on the user behavior modeling."
According to the news reporters, the research concluded: "We show by experiments that the proposed system represents a valid solution for interactive multiview systems with classical decoders."
