AVS2 is the new generation of video coding standard developed by the Audio Video Coding Standard Working Group of China. In analogies to HEVC/H.265, a more flexible CU (coding unit), PU (prediction unit) and TU (transform unit) based coding structure is adopted to represent and organize the coding data. For intra coding, AVS2 adopts quad tree based partition coding structure on CU level, and one CU...
Screen content coding (SCC) has evolved into the extension of the High Efficiency Video Coding (HEVC). Low-latency, real-time transport between devices in the form of screen content video is becoming popular in many applications. However, the complexity of encoder is still very high for intra prediction in HEVC-based SCC. This paper proposes a fast intra prediction method based on content property...
The second generation Audio-video Coding Standard (AVS2) is the latest video standard currently under the development of Audio-video Coding Standard (AVS) Workgroup of China for achieving higher coding efficiency than previous (AVS1). In intra luminance prediction of AVS2, the AVS2 video encoder has to compute the rate-distortion optimization (RDO) of 9 selected candidate prediction modes in order...
High Efficiency Video Coding (HEVC) achieves themost significant coding efficiency compared with all the existingvideo coding standards. However, the Intra encoding complexityis increased dramatically since the complex recursive searchalgorithm for the coding unit (CU) size decisions. In this paper, afast CU size decision algorithm based on Support Vector Machines(SVM) is proposed to further alleviate...
As the next generation standard of video coding, the High Efficiency Video Coding (HEVC) is intended to provide significantly better coding efficiency than all existing video coding standards. To improve the coding efficiency of intra frame coding, up to 34 intra prediction modes are defined in HEVC. The best mode among these pre-defined intra prediction modes is selected by rate-distortion optimization...
