Modeling Acceleration Properties for Flexible INTRA HEVC Complexity Control

It is a very well-known fact, that the high complexity of the High Efficiency Video Coding standard (HEVC) is the main hurdle for its wide deployment and use. To tackle this problem, a number of recent research outcomes exploit heuristic algorithms …

SVM Based Fast CU Partitioning Algorithm for VVC Intra Coding

Recently, Joint Video Experts Team (JVET) has completed the new Versatile Video Coding (H.266/VVC) standard. VVC employs a new block partition structure named quad-tree with nested multi-type tree (QTMT) to improve coding efficiency. However, the new …

Quality of Experience Evaluation for Streaming Video Using CGNN

One of the principal contradictions these days in the field of video i s lying between the booming demand for evaluating the streaming video quality and the low precision of the Quality of Experience prediction results. In this paper, we propose …

Reinforcement Learning Based Adaptive Bitrate Algorithm for Transmitting Panoramic Videos

Panoramic videos have become more and more popular now. 360-degree videos give users a better experience but put forward a higher request for network at the same time. Many kinds of solutions to meet the high need of bandwidth have been proposed, …

Improved intra angular prediction with novel interpolation filter and boundary filter

In this paper, two improved intra angular prediction methods are proposed to enhance coding performance. The first method applies new four-tap interpolation filter algorithm. The reference samples at fractional position are interpolated by DCT-based …

Fast depth decision with enlarged coding block sizes for HEVC intra coding of 4K ultra-HD video

High Efficiency Video Coding (HEVC), the latest video coding standard, achieves significantly better compression performance than the previous coding standards, especially for high resolution (2K, 4K, etc.) video coding. Intra frame coding adopts a …
