For High Efficiency Video Coding (HEVC) using block-based prediction, the discrete cosine transform (DCT), and quantization, a large number of DCT coefficients in a transform block (TB) are commonly found to be quantized to zero. A two-dimensional transform in HEVC is usually implemented by first applying a butterfly-based one-dimensional (1D) DCT to each row of the residual block, followed by ...

Intra coding in High efficiency video coding (HEVC) can significantly improve the compression efficiency using 35 intra-prediction modes for 2N×2N (N is an integer number ranging from six to two) luma blocks. To find the luma block with the minimum rate-distortion, it must perform 11932 different rate-distortion cost calculations. Although this approach improves coding efficiency compared to th...

Most of the existing deep learning based end-to-end image/video coding (DLEC) architectures are designed for non-subsampled RGB color format. However, in order to achieve a superior performance, many state-of-the-art block-based compression standards such as High Efficiency Video Coding (HEVC/H.265) and Versatile (VVC/H.266) primarily YUV 4:2:0 format, where U V components subsampled by conside...

High efficiency video coding (HEVC) has been finalized as the most widely utilized standard, jointly developed by ITU-T, VCEG, and MPEG. In HEVC, quad-tree structure of unit partition is one substantial modules provides significant gains following huge time. this paper, a rate–distortion-based network (RDNet) proposed to make decisions based on statistical features. RDNet composed prediction su...

High efficiency video (HEVC) coding made its mark as a codec which compress with low bit rate than preceding that is H.264, but the factor stop HEVC from many applications complex encoding procedure. The distortion optimisation (RDO) cost calculation in consume calculations. In this paper, we propose method to cross out issue of calculations by replacing traditional inter-prediction procedure b...

This thesis presents a highly parallelized and low latency implementation of the Sample Adaptive Offset (SAO) filter, as part of a High Efficiency Video Coding (HEVC) chip under development for use in low power environments. The SAO algorithm is detailed and an algorithm suitable for parallel processing using offset processing blocks is analyzed. Further, the SAO block hardware architecture is ...

Among a series of video coding standards jointly developed by ITU-T, VCEG, and MPEG, high-efficiency (HEVC) is one the most widely used today. Therefore, it still necessary to further reduce complexity HEVC. In HEVC standard, flexible partitioning procedure entitled “quad-tree partition” proposed significantly improve efficiency, which, however, leads high complexity. To intra-frame prediction,...

Screen content coding (SCC) is becoming increasingly important in various applications, such as desktop sharing, video conferencing, and remote education. When compared to natural cameracaptured content, screen content has different characteristics, in particular sharper edges. In this paper, we propose a novel intra prediction scheme for screen content video. In the proposed scheme, bilinear i...
