   Abstract
   

   This paper describes two methods for increasing the efficiency of the MPEG Immersive Video (MIV) coding standard. The methods manipulate the MIV-formatted atlas videos by considering the coding principles of the widely used video encoders, enhancing the encoding efficiency for the immersive video content. The first method, patch average color modification removes the constant component of all YCbCr components of each patch within atlases, resulting in the reduction of the number and magnitude of edges within a texture atlas video. The second proposed method changes the dynamic range of the geometry (depth) atlas, adapting to the quality of input depth maps. Both methods proposed by the authors of this paper were included into the Test Model for MPEG Immersive Video (TMIV), which is the reference implementation of the MIV codec. Moreover, the metadata syntax relating to the first proposed method was adopted to the ISO/IEC 23090-12 standard.

   A New Approach to Decoder-Side Depth Estimation in Immersive Video Transmission,

   Abstract
   

   This paper presents a novel approach to decoder-side depth estimation (DSDE) in immersive video transmission. The proposal improves the state-of-the-art coding approach by changing the encoding and decoding processes so that the decoder-side depth estimator can utilize partial geometry information about the scene from several available input depth maps. Proposed changes allow for significantly faster decoding and better quality of virtual viewports presented to the viewer. The paper proposes two approaches, namely input depth map assistance (IDMA) and extended IDMA (eIDMA), both compliant with the bitstream of MPEG immersive video (MIV) standard. IDMA involves sending full depth maps for a selected subset of input views, which are then used to refine and enhance the depth maps for the remaining views. In eIDMA, the decoder additionally reprojects decoded depth maps to the remaining views and enhances them with depth patches containing difficult-to-estimate areas. Proposed methods were tested under the ISO/IEC MPEG Video Coding common test conditions for MIV. The combination of two proposals, the adaptive IDMA, was shown to outperform the current state-of-the-art DSDE approach in the rendered video quality and the computational complexity of decoder. MPEG experts have appreciated the proposed approaches, which will comply with a new DSDE profile of the incoming second edition of the MIV standard.

    Full textEndNoteCitationDOI
    
    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.

    IV-PSNR – the objective quality metric for immersive video applications,

    Abstract
    

    This paper presents a new objective quality metric that was adapted to the complex characteristics of immersive video (IV) which is prone to errors caused by processing and compression of multiple input views and virtual view synthesis. The proposed metric, IV-PSNR, contains two techniques that allow for the evaluation of quality loss for typical immersive video distortions: corresponding pixel shift and global component difference. The performed experiments compared the proposal with 31 state-of-the-art quality metrics, showing their performance in the assessment of quality in immersive video coding and processing, and in other applications, using commonly used image quality assessment databases – TID2013 and CVIQ. As presented, IV-PSNR outperforms other metrics in immersive video applications and still can be efficiently used in the evaluation of different images and videos. Moreover, basing the metric on the calculation of PSNR allowed the computational complexity to remain low. Publicly available, efficient implementation of IV-PSNR software was provided by the authors of this paper and is used by ISO/IEC MPEG for evaluation and research on the upcoming MPEG Immersive video (MIV) coding standard.

     Segmentation-based Method of Increasing The Depth Maps Temporal Consistency,

     Abstract
     

     In this paper, a modification of the graph-based depth estimation is presented. The purpose of proposed modification is to increase the quality of estimated depth maps, reduce the time of the estimation, and increase the temporal consistency of depth maps. The modification is based on the image segmentation using superpixels, therefore in the first step of the proposed modification a segmentation of previous frames is used in the currently processed frame in order to reduce the overall time of the depth estimation. In the next step, a depth map from the previous frame is used in the depth map optimization as the initial values of a depth map estimated for the current frame. It results in the better representation of silhouettes of objects in depth maps and in the reduced computational complexity of the depth estimation process. In order to evaluate the performance of the proposed modification the authors performed the experiment for a set of multiview test sequences that varied in their content and an arrangement of cameras. The results of the experiments confirmed the increase of the depth maps quality — the quality of depth maps calculated with the proposed modification is higher than for the unmodified depth estimation method, apart from the number of the performed optimization cycles. Therefore, use of the proposed modification allows to estimate a depth of the better quality with almost 40% reduction of the estimation time. Moreover, the temporal consistency, measured through the reduction of the bitrate of encoded virtual views, was also considerably increased.

     Abstract
     

     The paper reports the results on virtual navigation in a sports hall. The video data is gathered and processed off-line thus producing the multiview plus depth representation of a scene. This representation is an input to the rendering server. Even a typical PC computer is able to serve a number of users that freely and independently navigate in real - time and watch virtual video. The users are able to navigate in the scene changing the virtual viewpoint and virtual view direction. The service is provided through a webpage, so a viewer does not need to install any software on smartphone, tablet or notebook. The paper discusses the technical solutions together with the rationale for their choice.

     Abstract
     

     This article presents a processing pipeline for rendering servers used in free viewpoint television systems to provide virtual views requested by the user of the free navigation service. Such functionality requires a processing scheme to ensure a fast synthesis of virtual views and to operate with very large amount of data, because FTV systems are characterized by the large number of used cameras. The proposed solutions heavily utilize parallelization and multithreaded operations, together with the use of WebSocket. The proposal was to show that the solution guarantees the delivery of the new virtual view in real time, what ensures the high quality of the experience for the user of the free navigation service.

     This paper presents a new method of estimation of camera parameters which uses spherical structures as calibration objects. The method allows estimation of intrinsic parameters and parameters of the optical distortion of a camera and is adapted to the multi-camera systems. The algorithms shown in the paper, as well as implementations of the optical center and lens distortion coefficients estimation use novel solutions developed for the purpose of this paper. The presented method is tested experimentally by the authors. The results of the experiment prove that the method provides the accuracy of the estimation of the camera parameters comparable to the widely used state-of-the-art methods, therefore can be successfully used with any multi-camera

     Abstract
     

     In the article we deal with the problem of camera positioning in sparse multiview systems with applications to free navigation. The limited number of the cameras, though makes the system relatively practical, implies problems with proper depth estimation and virtual view synthesis, due to increased amount of the occluded areas. We present experimental results for the optimal positioning of the cameras, depending on two factors – characteristics of an acquired scene and the multi-camera system (linear or circular camera setup). The results show the correlation between the number of occlusions in the scene and a gain from using camera pairs instead of uniformly distributed cameras.

     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 propose a new method for the virtual view synthesis called as Multiview Synthesis. In our approach, virtual views are synthesized using two neighboring real views, but the disoccluded areas are not inpainted, but filled by the information from the further real views – additional views, traditionally not included in the view synthesis. The whole synthesis is performed with triangles rather than with individual pixels. In the proposed Multiview Synthesis, additional steps of adaptive color correction, blurred edge removal and spatial edge blurring are also included. The experimental results show that both the objective and subjective quality of the synthesized views is significantly higher than the quality of views obtained using the state-of-the-art MPEG reference view synthesis software.

     Abstract
     

     The paper considers the influence of a lossy compression of multiview video on the quality of estimated depth maps. We have encoded a set of views with commonly known compression techniques used in compact IP cameras: HEVC (MPEG H part 2 / H.265), AVC (MPEG 4 part 10 / H.264) and MPEG 2 part 2 / H.262. Basing on the decoded data we have estimated depth maps and rendered a set of the intermediate virtual views. A drop of the quality was studied by comparison of virtual views rendered out of the depth maps estimated from an uncompressed video. The obtained results show that with a reasonable compression rate, lower quality of virtual views is acceptable for real implementable FTV systems.

     Abstract
     

     In free-viewpoint television, high-quality depth maps are substantial for a virtual view synthesis for free navigation purposes. In this paper, we propose a new method of depth map quality improvement and resolution increase. Our method is intended for low resolution depth maps acquired through estimation using multiview video. The proposed depth map quality improvement is based on segmentation of an acquired high-resolution image. In the estimated depth map, searching for outliers is performed in the neighborhood created from similar segments in the acquired view. Experimental results show high effectiveness of the presented method of depth maps refinement, especially for object edges.

     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.
