    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.

    Abstract

    In the paper, two preprocessing methods for virtual view synthesis are presented. In the first approach, both horizontal and vertical resolutions of the real views and the corresponding depth maps are doubled in order to perform view synthesis on images with densely arranged points. In the second method, real views are filtered in order to eliminate blurred or improperly shifted edges of the objects. Both methods are performed prior to synthesis, thus they may be applied to different Depth-Image-Based Rendering algorithms. In the paper, for both proposed methods, the achieved quality gains are presented.

    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 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.

    Abstract

    In this paper we introduce an algorithm for omnidirectional virtual view synthesis based on Omnidirectional Video plus Depth (OVD) format. The implementation is done on the basis of View Synthesis Reference Software (VSRS) developed by MPEG of ISO/IEC. Also, we address the problem of lack of benchmark data disallowing objective quality assessment. We present a method for generating test images in OVD representation along with example omnidirectional images and omnidirectional depths, called “Poznan Hall 360”.

    Abstract

    This paper presents the fast virtual view synthesis method for free navigation purposes. Presented method was implemented on CPU in order to allow free navigation for even cheap personal computers with integrated graphic cards. The described synthesis technique is based on the hybrid view synthesis, combining advantages of forward-type and backward-type synthesis. It allows to synthesize high resolution sequences in the real time, allowing the viewer to freely navigate around the scene, e.g. volleyball playfield. Three implementations were developed and tested: single-threaded, vectorized and multi-threaded implementation.

    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.

    New results in free-viewpoint television systems for horizontal virtual navigation,

    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.

    The influence of a lossy compression on the quality of estimated depth maps,

    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.

    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.
