    Abstract

    Optimization of encoding process in video compression is an important research problem, especially in the case of modern, sophisticated compression technologies. In this paper, we consider HEVC, for which a novel method for selection of the encoding modes is proposed. By the encoding modes we mean e.g. coding block structure, prediction types and motion vectors. The proposed selection is done basing on noise-reduced version of the input sequence, while the information about the video itself, e.g. transform coefficients, is coded basing on the unaltered input. The proposed method involves encoding of two versions of the input sequence. Further, we show realization proving that the complexity is only negligibly higher than complexity of a single encoding. The proposal has been implemented in HEVC reference software from MPEG and tested experimentally. The results show that the proposal provides up to 1.5% bitrate reduction while preserving the same quality of a decoded video.

    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

    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

    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.

    Full textEndNoteCitation

    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.

    Pruning in picture reference list in HEVC,

    Abstract

    Possibility of selection of a particular reference picture from many previously encoded frames is one of the reasons of significant extension of time necessary for encoding of a video sequence with HEVC. Search of motion vectors within all available reference pictures for every PU (allowed by the HEVC standard) and selecting the best one, significantly enhances coding effectiveness but requires big computational effort leading to long encoding time. A fast method for selection of the best reference picture would be a source of shortening of the encoding time. This documents reports and verifies a method for fast reference picture selection in which reference picture list is pruned basing on the size of the PU under consideration. This way the number of reference picture necessary to look at the during motion vector search is reduced. Foundations of the reported method are the results of statistical analysis of the actual selected reference picture (considered by the encoder as the best in terms of RD) during encoding of the particular PU size.

    The paper presents analysis and comparison of complexity of selected algorithms of motion estimation used in video compression. With the use of own, highly optimized software implementation the authors explored complexity of the methods applied in the framework of the new High Efficiency Video Compression (HEVC) technology. The influence of many different factors on motion estimation complexity has been deeply studied, including the implementation technique, type of the algorithm, number of processor threads used, kind of metric of blocks similarity. The results obtained allowed to formulate guidelines and conclusions that may be useful for future implementation of motion estimation algorithms in context of HEVC encoders.

    Compression of moving images has opened unprecedented opportunities of transmission and storage of digital video. Extraordinary performance of today’s video codecs is a result of tens of years of work on the development of methods of data encoding. This paper is an attempt to show this history of development. It highlights the history of individual algorithms of data encoding as well as the evolution of video compression technologies as a whole. With the development of successive technologies also functionalities of codecs were evolving, which make also the topic of the paper. The paper ends the attempt of authors’ forecasting about the future evolution of video compression technologies.

    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 results of the experiments conducted on the HEVC encoder, regarding the complexity and performance of the motion estimation algorithm. The research focuses on the search range of motion vectors and its influence on the encoding time of the video with the use of a HEVC encoder, as well as on the method for choosing the starting point of the motion estimation algorithm. Performance is measured as the time reduction and Bjontegaard metric bitrate reduction.

    Depth estimation based on maximization of A posteriori probability,
    International Conference on Computer Vision and Graphics ICCVG 2016, Warsaw, Poland, 19-21 September 2016,
    Full textEndNoteCitation

    Abstract

    This paper presents a proposal of depth estimation method which employs empirical modeling of cost function based on Maximization of A posteriori Probability (MAP) rule. The proposed method allows for unsupervised depth estimation without a need for usage of arbitrary settings or control parameters, like Smoothing Coefficient in Depth Estimation Reference Software (DERS), which was used as a reference. The attained quality of generated depth maps is comparable to a case when supervised depth estimation is used, and such parameters are manually optimized. In the case when sub-optimal settings of control parameters in supervised depth estimation with DERS is used, the proposed method provides gains of about 2.8dB measured in average PSNR quality of virtual views synthesized with the use of estimated depth maps in the tested sequence set. 1

    Abstract

    In this paper, a detailed analysis of the content of the bitstream, produced by the HEVC video encoder is presented. With the use of the HM 10.0 reference software the following statistics were investigated: 1) the amount of data in the encoded stream related to individual frame types, 2) the relationship between the value of the QP and the size of the bitstream at the output of the encoder, 3) contribution of individual types of data to I and B frames. The above mentioned aspects have been thoroughly explored for a wide range of target bitrates. The obtained results became the basis for highlighting guidelines that allow for efficient bitrate control in the HEVC encoder.

    Abstract

    For the new HEVC compression technology, the analysis of accumulation of quality losses in multi-generation coding is still an open problem. In this paper, we describe the results of extensive experiments that demonstrate quality loss accumulation in 300 encoding-decoding cycles using the HEVC codec in the All Intra mode. For consecutive encoding cycles with constant encoder configuration, the coding quality loss decrease much slower than for JPEG 2000. However, for SD resolution, the HEVC intra-only encoder provides lower bitrates than JPEG 2000 with the same video quality. Therefore, even after 300 cycles, the HEVC All Intra usually provides lower bitrates than JPEG 2000 with the same decoded-video quality.

    This paper presents detailed analysis of the CABAC efficiency when operating in the HEVC in a number of bits per number of bins manner. The paper reveals what fraction of bit is produced by the CABAC for each and every binary symbols encoded in HEVC. The statistics of bins encoded with a given efficiency are presented for the three types of video data: 1) prediction error of image samples, 2) motion data, and 3) control data.

    Abstract

    The paper focuses on two problems: 1) analysis of bitrate contribution of I and B frames in encoded HEVC data stream, and 2) analysis of distribution of HEVC syntax elements in I and B frames. The relationship between sizes of I and B frames located at a different levels in hierarchical coding scheme was experimentally determined, as well as contribution of HEVC syntax elements in encoded streams of I, B0, B1, B2, and B3 frames. The results are presented in the paper. All presented results concern a wide range of QP values in a video encoder.

    Abstract

    The paper presents analysis of frame partitioning in the next generation video coding standard HEVC. Complex study on frequency of the particular coding unit, prediction unit and transform unit sizes selection made by the encoder compliant with HEVC technology is included. General conclusions based on extensive experiments for HD video sequences are presented. Such knowledge may be the first step to the development of more efficient mode selection algorithms.

    Abstract

    We propose a new coding technology for 3D video represented by multiple views and the respective depth maps. The proposed technology is demonstrated as an extension of the recently developed high efficiency video coding (HEVC). One base views are compressed into a standard bitstream (like in HEVC). The remaining views and the depth maps are compressed using new coding tools that mostly rely on view synthesis. In the decoder, those views and the depth maps are derived via synthesis in the 3D space from the decoded baseview and from data corresponding to small disoccluded regions. The shapes and locations of those disoccluded regions can be derived by the decoder without any side information transmitted. To achieve high compression efficiency, we propose several new tools such as depth-based motion prediction, joint high frequency layer coding, consistent depth representation, and nonlinear depth representation. The experiments show high compression efficiency of the proposed technology. The bitrate needed for transmission of two side views with depth maps is mostly less than 50% than that of the bitrate for a single-view video.

    Abstract

    An image coding method. The method includes encoding a first image, the first image having a reduced spatial resolution relative to an input image, wherein values of the first image depend on energy of corresponding areas of the input image, and encoding a first shape information of the shape of a spatial spectrum of the input image. The method further includes reconstructing a second image from the encoded first image, reconstructing a second shape information from the encoded first shape information, and generating a noise image having an intensity described by the second image and having a spectrum shape described by the second shape information.

    Abstract

    At a receiver terminal, true 3D video provides ability to watch views selected from a large number of available views. Such ability is needed for the forthcoming 3D video applications like free-view television, autostereoscopic displays etc. Delivery of many views through communication channels is a challenging problem that has to be solved in the near future. In this paper, we study delivery of real 3D video using the state-of-the-art compression technology. Considered are the issues related to 3D video data model as well its application for generation of video from arbitrary virtual viewpoint. Included are respective experimental results.
