Intra Coding With Adaptive Partial Reconstruction

IEEE Transactions on Circuits and Systems for Video Technology, 2013
Intra prediction improves coding performance by reducing inter pixel redundancy. However, to accommodate the use of block transforms, not all pixels can be predicted from reconstructed pixels that are located close to themselves. This causes prediction performance to suffer as pixel values further apart are less correlated.

Multi-mode based intra prediction coding

2015 8th International Congress on Image and Signal Processing (CISP), 2015
In multi-mode based data processing schemes, the most appropriate mode is selected as the one for application under the comparison of different kinds of available modes, it has been applied in scanning image quantized coefficients and image prediction coding maturely to improve the processing efficiency and coding efficiency.

Intra picture coding with planar representations

28th Picture Coding Symposium, 2010
In this paper we introduce a novel concept for Intra coding of pictures especially suitable for representing smooth image segments. Traditional block based transform coding methods cause visually annoying blocking artifacts for image segments with gradually changing smooth content.

Fast Coding Unit Depth Decision for HEVC Intra Coding

2017
To reduce the complexity of High Efficiency Video Coding (HEVC), this paper focuses on innovative works for fast coding tree unit (CTU) depth decision in HEVC intra coding based on a proposed CTU depth range possibility mechanism. First, the depth correlation factor (DCF) is computed by analyzing the temporal-spatial correlation of the co-located CTU ...

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.

Intra-predictive transforms for image coding

2009 IEEE International Symposium on Circuits and Systems, 2009
This paper presents a new transform framework, intra-predictive transforms, for block-based image coding. The proposed framework unifies cross-block prediction and transforms within a block. Thus, it can exploit both the intra- and inter- block correlations.
