Enhanced intra prediction for inter pictures

2017 IEEE International Conference on Multimedia and Expo (ICME), 2017
This paper presents a novel intra prediction method for inter pictures (i.e. P pictures and B pictures), denominated enhanced intra prediction (EIP). The traditional intra prediction only uses the reconstructed pixels to the left and above to derive intra prediction blocks.

Intra-prediction with adaptive sub-sampling

2011 18th IEEE International Conference on Image Processing, 2011
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.

A Software Fault Prediction on Inter- and Intra-Release Prediction Scenarios

International Journal of Open Source Software and Processes, 2021
Software quality engineering applied numerous techniques for assuring the quality of software, namely testing, verification, validation, fault tolerance, and fault prediction of the software. The machine learning techniques facilitate the identification of software modules as faulty or non-faulty.

Hybrid angular intra/template matching prediction for HEVC intra coding

2015 Visual Communications and Image Processing (VCIP), 2015
In the latest HEVC video coding standard, angular intra prediction (AIP) applies 35 modes including 33 angular modes which can handle blocks with direction information well, and other 2 modes (DC and planar) which are used to predict smooth blocks. However, for blocks with complex texture, these modes may not give good predictions.

Intra Line Copy for HEVC Screen Content Intra-Picture Prediction

IEEE Transactions on Circuits and Systems for Video Technology, 2017
This paper presents an intra line copy (ILC) technique for HEVC screen content coding. It shares the same origin with two other prominent techniques, intra string copy (ISC) and intra block copy (IBC), in applying the notion of string matching to intra-frame coding.

A Fast Intra Prediction Algorithm for HEVC

2012
A new fast intra-prediction algorithm for HEVC is proposed in this paper. The algorithm makes full use of spatial correlations among video sequences, decides the best size of CU by referring neighboring coded CUs’ size and the best prediction mode of PU by referring the up layer PU modes.

Intra prediction with deep learning

Applications of Digital Image Processing XLI, 2018
One fundamental component of video compression standards is Intra-Prediction. Intra-Prediction takes advantage of redundancy in the information of neighboring pixel values within video frames to predict blocks of pixels from their surrounding pixels and thus allowing to transmit the prediction errors instead of the pixel values themselves.

Intra prediction based on interpolation

Proceedings of 2011 International Conference on Computer Science and Network Technology, 2011
Intra Prediction is a good method to improve compression ratio. At present, Block as the basic prediction unit is adopted in prediction algorithm. The predict value of current point is searched and calculated from the adjacent point, its predictive result is closely related with the image features and the search process is very complexity.

Intra prediction with spatial gradient

SPIE Proceedings, 2009
ABSTRACT Spatial intra prediction has been added recently to the latest video coding standard H.264/AVC. In the intraprediction of H.264/AVC, there are 9, 9 and 4 prediction modes for 4 × 4, 8 × 8and16× 16 blocks, respectively.Prediction signals are generated by using one or several reference pixels.

Intra predictive transform coding based on predictive graph transform

2013 IEEE International Conference on Image Processing, 2013
In this paper, we propose a new intra-frame coding approach using the predictive graph transform (PGT). The predicted block together with the reference pixels are modeled as a normal distributed random vector with respect to a graph whose edges represent the correlations between pixels. This model is more flexible than the Gaussian Markov random field (
