The new high efficiency video coding standard (HEVC) includes structures and tools that were not available in previous standards. The macrobock concept was replaced by a quad-tree structure that includes: coding units, prediction units and transform units; also, new parallelization tools are now available. Video transmissions over error prone environments have the need of reliable and efficient...

Similar to previous video coding standards, transform and quantization are employed in the most recent video coding standard High Efficiency Video Coding (HEVC), and there exist a large number of transform coefficients being quantized to zeros. In order to reduce the computations in transform and quantization, a novel prediction algorithm is designed to early detect all-zero 4 4 blocks prior to...

This paper, deals with the currently under-development video encoding standard H.265/HEVC. The main purpose of this paper is to perform a quantitative performance evaluation of the emerging standard in comparison to its predecessor H.264/AVC. The paper focuses on both the encoding and compression efficiency by measuring the PSNR scores and bit rate values of reference and non-reference signals....

A JPEG1988 coding system extended by Speckle adaptive quantization and improved entropy coding is compared against the standard coding systems JPEG1988, JPEG2000, MPEG4-AVC and HEVC with regard to their coding efficiency related to SAR images. A Speckle adaptive quantization is presented that exploits the masking potential of the Speckle noise to achieve additional data compression. For coding ...

In this paper, we propose a video compression algorithm based on human visual perception for High Efficiency Video Coding (HEVC). The proposed algorithm is applied to the conventional lossy coding to reduce bitrate without any further subjective quality degradation. It improves coding performance by allowing objective quantization error which is not noticeable to human visual system (HVS). By u...

HEVC (High Efficiency Video Coding) is the next-generation video coding standard, which introduced many new technologies such as tree structure coding unit and a variety of intra prediction mode. Compared with H.264/AVC, HEVC has achieved higher coding efficiency but requires a very high computational complexity. So this paper proposes a fast algorithm through early termination of the CU (Codin...

This work proposes a novel architecture for intra prediction image generation of High Efficiency Video Coding (HEVC) standards oriented to FPGA. HEVC intra prediction is highly-extended from H.264 in those of mode and block size to realize the high flexibility. From the point of view of hardware, however, this flexibility cause an increasing required the number of MUXs although MUXs tend to be ...
