Fast template matching for intra prediction

2017 IEEE International Conference on Image Processing (ICIP), 2017
Intra prediction is an important step in video coding, where spatial redundancy is exploited for coding efficiency. The state-of-the-art H.265/High Efficiency Video Coding (HEVC) standard provides 35 intra prediction modes including 33 angular modes and a DC as well as a Planar mode. Although these intra prediction methods are quite efficient, there is

On the coding gain of intra-predictive transforms

2009 16th IEEE International Conference on Image Processing (ICIP), 2009
Intra-predictive transforms are a kind of block-based transforms that can exploit both the intra- and inter-block correlations. This paper analyzes the coding gains of intra-predictive transforms for the Gaussian process. The tight upper bound of the coding gain is derived, which is shown to be better than both the discrete cosine transform and the ...

Tree structured hybrid intra prediction

2004 International Conference on Image Processing, 2004. ICIP '04., 2005
This paper proposes a new method to generate intra prediction images in intra coding, tree structured hybrid intra prediction. When generating intra prediction images, the proposed method selects the most suitable one from intra prediction images generated using two methods, pixel-based and block-based intra prediction.

Adaptive spatial prediction in intra coding

Proceedings of 2010 IEEE International Symposium on Circuits and Systems, 2010
In this paper, a novel spatial prediction method is proposed to improve prediction accuracy and capture the dynamics of different video contents. The method adaptively generates optimized spatial prediction modes according to the local feature of coded image.

A Novel Architecture Of AVS2 Intra Prediction

2020 IEEE International Conference on Consumer Electronics (ICCE), 2020
AVS2 is the latest generation of video coding standard independently developed by China. In this paper a parallel hardware structure of ASIC for AVS2 intra prediction encoding is proposed. This architecture is analyzed by the algorithm and take advantage of the ASIC parallelism.

Intra prediction modes signalling in HEVC

2016 Picture Coding Symposium (PCS), 2016
The High Efficiency Video Coding (HEVC) standard defines 35 Intra Prediction Modes (IPM) to provide an efficient compression of intra coded blocks. To signal these IPMs to the decoder a list of 3 Most Probable Modes (MPM) is created based on the IPMs of the neighbour Intra coded blocks.

Parallel intra prediction for video coding

28th Picture Coding Symposium, 2010
In this paper, we propose an intra-prediction system that is both parallel friendly and with high coding efficiency. This is achieved by combining a novel prediction strategy that reduces serial dependencies and a novel, multi-directional and adaptive prediction system.

Rectangular partitioning for Intra prediction in HEVC

2012 Visual Communications and Image Processing, 2012
This paper presents a mechanism of using rectangular prediction blocks for Intra prediction in the emerging High Efficiency Video Coding (HEVC) standard. In the previous and current video coding standards, Intra predictions have been processed on square blocks, e.g.

Intra-prediction Techniques

2016
In this chapter, the very basic introduction about video compression theory is introduced. In this context, different redundancies which are generally exploited in video compression are discussed in detail. After that, the hybrid video codec is explained in brief.

Improving chroma intra prediction for HEVC

2016 IEEE International Conference on Multimedia & Expo Workshops (ICMEW), 2016
YCbCr color space is widely used in previous video coding standards such as H.264 and the latest video coding standard HEVC. Although the conversion from RGB to YCbCr reduces the inter-channel redundancy significantly, there are still some correlations among Y, Cb and Cr.
