The multi-view HEVC (MV-HEVC) extension was finalized in July of 2014 by the Moving Picture Experts Group and the Video Coding Experts Group. Recently, multi-view videos based on stereo representations are becoming widely popular. Also, a variety of multimedia contents are now available for mobile devices. A real-time multi-view video decoder is therefore needed. In mobile devices, a real-time ...

Visual sensor networks (VSNs) can be widely applied in security surveillance, environmental monitoring, smart rooms, etc. However, with the increased number of camera nodes in VSNs, the volume of the visual information data increases significantly, which becomes a challenge for storage, processing and transmitting the visual data. The state-of-the-art video compression standard, high efficiency...

As the next generation of video coding standard, High Efficiency Video Coding (HEVC) adopted many useful tools to improve coding efficiency. Sample Adaptive Offset (SAO), is a technique to reduce sample distortion by providing offsets to pixels in in-loop filter. In SAO, pixels in LCU are classified into several categories, then categories and offsets are given based on Rate-Distortion Optimiza...

The H.264/AVC standard achieves much higher coding efficiency than the H.263, MPEG-2 and MPEG-4 standard, due to its improved inter and intra-prediction modes at the expense of higher computation complexity. Throughout the evolution of video coding standards, continued efforts have been made to maximize compression capability and improve other characteristics such as data loss robustness, while...

High Efficiency Video Coding (HEVC) is the most recent video codec standard of the ITU-T Video Coding Experts Group and the ISO/IEC Moving Picture Experts Group. The main goal of this newly introduced standard is for catering to high-resolution video in low bandwidth environments with a higher compression ratio. This paper provides a performance comparison between HEVC and H.264/AVC video compr...

Introducing a number of innovative and powerful coding tools, the High Efficiency Video Coding (HEVC) standard promises double compression efficiency, compared to its predecessor H.264, with similar perceptual quality. The increased computational time complexity is an important issue for the video coding research community as well. An attempt to reduce this complexity of HEVC is adopted in this...

An energy-efficient distributed Scratchpad Video Memory Architecture (dSVM) for the next-generation parallel High Efficiency Video Coding is presented. Our dSVM combines private and overlapping (shared) Scratchpad Memories (SPMs) to support data reuse within and across different cores concurrently executing multiple parallel HEVC threads. We developed a statistical method to size and design the...

Visual Display Units (VDUs), capable of displaying video data at High Definition (HD) and Ultra HD (UHD) resolutions, are frequently employed in a variety of technological domains. Quantization-induced video compression artifacts, which are usually unnoticeable in low resolution environments, are typically conspicuous on high resolution VDUs and video data. The default quantization matrices (QM...

For extension of High Efficient Video Coding (HEVC), a high quality experience is offered by using three-dimensional (3-D) video. Also, the primary usage scenario for multiview video is to support 3-D video applications, where 3-D depth perception of a visual scene is provided by a 3-D display system. The efficient representation and compression of stereo and multiview video is a central compon...

Versatile Video Coding (VVC/H.266) is an emerging successor to the widespread High Efficiency (HEVC/H.265) and shown double coding efficiency for same subjective visual quality. Nevertheless, VVC still adopts similar hybrid video scheme as HEVC thereby sets scene reusing many tools techniques or with minor modifications. This paper explores feasibility of developing a practical software intra e...
