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...

three dimensional- high efficiency video coding (3D-HEVC) is the expanded version of the latest video compression standard, namely high efficiency video coding (HEVC), which is used to compress 3D videos. 3D videos include texture video and depth map. Since the statistical characteristics of depth maps are different from those of texture videos, new tools have been added to the HEVC standard fo...

An intra prediction method that uses neighbor pixels within current picture has been adopted for improving coding efficiency, but the intra prediction having a large number of prediction modes increases the implementation operation at the encoder side. In order to reduce the operation, we first investigate the usage distribution of the intra prediction modes according to the coded picture chara...

Intra prediction is a fundamental prediction type in blockbased video coding, which has been adopted by the most recent finalized standard H.264/AVC. H.264/AVC has specified several intra prediction modes that predict the current block through surrounding spatial neighboring pixels in a causal window along various directions. In this paper, we investigate the use of linear prediction for intra ...

Inter prediction and intra prediction are utilized by video coding standard H.264/AVC to exploit the temporal and spatial redundancy respectively. To further improve coding efficiency, combined inter and intra prediction was proposed to produce more accurate prediction signal. However, these methods suffer from either high computation or limited improvement. In this paper we present an efficien...

This paper proposes simulation of Intra frame coding in Advanced Video Coding Standard using Intra Prediction. The simulation results of Compression ratio and PSNR for with and without prediction are presented using Matlab. To perform Intra frame coding in AVC requires intra prediction in intra prediction there are nine prediction modes such as vertical, horizontal, dc,diagonal down left, diago...

In H.264/AVC standard, the intra-frame prediction scheme is employed for better coding efficiency. Using the already encoded adjacent upper and left pixels, the intra prediction is performed. In this paper, we present an improved intra prediction scheme of H.264/AVC. By taking into account the error of the adjacent bottom and right pixels in intra mode decision, our scheme shows better results ...
