Abstract :
We propose a free viewpoint video communication method that allows the user to change his/her viewing point and viewing direction freely. This application will be a next generation visual application in the near future. We propose suitable multiple view video coding method and communication protocol for this communication application, and demonstrate the coding efficiency of the proposed method. We also demonstrate that the developed viewer can generate the view of arbitrary viewpoint and view direction. This viewer uses the Ray-Space interpolation and extrapolation methods and generates a natural view.
