    Hierarchical fast selection of intraframe prediction mode in HEVC,

    Full textEndNoteCitationDOI

    Abstract

    In the new HEVC standard, there are 35 intraframe prediction modes. Therefore, real-time implementations need fast mode pre-selection to reduce the computational load of cost comparison for individual modes. In this paper, a simple technique is proposed to reduce the complexity of the Unified Intra Prediction by decreasing the mode candidate number evaluated in the Rough Mode Decision step. We call this approach hierarchical as we decrease stepwise the angles between the directions of the prediction modes that are tested. Obviously, the fast mode selection results in significant complexity reduction obtained at the cost of choosing a sub-optimum mode related to slightly reduced compression performance. In the paper, it is proposed how to calculate the trade-off between encoder complexity and compression performance, using the ratio of relative coding time reduction and average bitrate increase estimated for constant decoded video quality. Extensive experiments prove that this ratio is much higher for the proposed technique than for many other techniques from the references.

    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

    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.

    Digital Watermarking with Local Strength Adjustment for AVC-Compressed HDTV Bitstreams,

    Full textEndNoteCitationDOI

    Abstract

    A computationally inexpensive watermark schema for MPEG-4 AVC/H.264 streams that use local mark strength adjustment minimizing visible artifacts is presented. The local mark strength adjustment mechanism and watermark embedding mechanism operate on residual data. This approach minimize the number of operations needed for video bitstream decoding and subsequent watermarked video data encoding. The experimental results included herein, described for real-world MPEG4 AVC/H.264 encoded HDTV video bitstreams prove its robustness to complex attacks, especially camcorder recording attack.

    High Efficiency 3D Video Coding Using New Tools Based on View Synthesis,

    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.
