   Abstract
   

   This paper presents the modified HEVC Screen Content Coding (SCC) that was adapted to be more efficient as an internal video coding of the MPEG Immersive Video (MIV) codec. The basic, unmodified SCC is already known to be useful in such an application. However, in this paper, we propose three additional improvements to SCC to increase the efficiency of immersive video coding. First, we analyze using the quarter-pel accuracy in the intra block copy technique to provide a more effective search of the best candidate block to be copied in the encoding process. The second proposal is the use of tiles to allow inter-view prediction inside MIV atlases. The last proposed improvement is the addition of the MIV bitstream parser in the HEVC encoder that enables selecting the most efficient coding configuration depending on the type of currently encoded data. The experimental results show that the proposal increases the compression efficiency for natural content sequences by almost 7% and simultaneously decreases the computational time of encoding by more than 15%, making the proposal very valuable for further research on immersive video coding.

    Abstract
    

    The paper deals with the problem of the optimal selection of the real views used for the virtual view synthesis in the free navigation systems. The practical free navigation system requires the real-time view synthesis. Therefore, the virtual view cannot be synthesized using the information from all the real cameras, but only few, most proper ones. In the paper the method of fast selection of two proper real views is presented. The proposed approach allows to select the real views for different camera arrangements, thus can be applied to the practical free navigation systems

    Abstract
    

    The paper presents the concept of a practical free-viewpoint television system with purely optical depth estimation. The system consists of camera modules that contain pairs or triples of cameras together with the respective microphones. The camera modules can be sparsely located in arbitrary positions around a scene. Each camera module is equivalent to a video camera with a depth sensor and microphones. The hardware requirements, the video and audio processing algorithms and the preliminary experimental results are reported. In particular, for such systems, a compression technique is discussed that is more efficient than the new 3D-HEVC technology. A set of new test sequences obtained with the use of camera pairs are presented.

    Abstract
    

    In the paper, we describe the extensions of the 3D HEVC compression technology aimed at improved compression efficiency for multi-view sequences acquired from arbitrarily located cameras. Our proposal refines the inter-view prediction by replacing the horizontal shifts with the true mapping in the 3D space. This implies changes in several coding tools, which we describe in details. The paper also reports experimental results on the comparison of the proposed solution to the 3D-HEVC standard codec. We also discuss the influence of the number of views and the view coding order on the compression efficiency.

    Abstract
    

    The paper reports the hitherto obtained results of the research project that deals with scene representations that are suitable for free navigation around the scene. These scene representations are acquired from a limited number of cameras located around the scene. The project is aimed at the development of an efficient compression technology and the experimental environment for testing such technology. The paper reports some new multiview test sequences with the circular camera arrangement, including the hybrid ones that have been acquired using also the depth sensors. Finally, the paper also briefly reports the recent results of the new compression technology being under development. This technology outperforms the state-of-the-art 3D-HEVC.
