An Intra Subpartition Coding Mode for VVC

2019 IEEE International Conference on Image Processing (ICIP), 2019
The upcoming Versatile Video Coding (VVC) Standard includes various new intra prediction tools that were not present in its predecessor High Efficiency Video Coding (HEVC), such as the wide angle intra prediction, the position dependent prediction combination or the multiple reference line intra prediction.

A fast intra coding algorithm for HEVC

2014 IEEE International Conference on Image Processing (ICIP), 2014
High Efficiency Video Coding (HEVC) is the emerging video coding standard, which provides equivalent subjective quality with about 50% bit rate reduction compared to H.264/AVC High Profile. However, the improvement of coding efficiency is obtained at the expense of increased computational complexity.

A Selective Intra-Coding Approach for Multiple Description Video Coding

2016 IEEE International Symposium on Multimedia (ISM), 2016
Multiple Description Coding (MDC) is a technique for video transmission over error prone networks where the descriptions are routed over multiple paths. Intra coding technique and MDC both provides error resiliency for real-time video transport over unreliable networks. In this paper, we present our investigation results for a new intra coding approach

Intra-picture Coding

, 2015
Still (or intra-picture) image coding includes compression of binary images and images with multiple amplitude levels, the latter case either monochrome or with multiple color components, as typically captured by cameras or image scanners. Beyond that, compression schemes are also applied to other sensor data such as magnetic resonance intensity in ...

Short Distance Intra Coding Scheme for High Efficiency Video Coding

IEEE Transactions on Image Processing, 2013
This paper proposes a new intra coding scheme, known as short distance intra prediction (SDIP), for high efficiency video coding (HEVC) standardization work. The proposed method is based on the quadtree unit structure of HEVC. By splitting a coding unit into nonsquare units for coding and reconstruction, and therefore shortening the distances between ...
