Fast Intra Mode Decision Algorithm Based on Mode Correlation in SVC

Applied Mechanics and Materials, 2013
Intra4×4 mode decision has correlation between enhancement layer and base layer in scalable video coding (SVC). In this paper, a new intra mode decision algorithm is proposed based on this correlation and the proximity of prediction directions of nine Intra4×4 prediction modes.

An efficient fast intra mode decision method based on orthogonal modes elimination

IEEE Transactions on Consumer Electronics, 2012
One of the computationally intensive stages in the H.264/AVC encoder is intra prediction. This is because rate-distortion optimization (RDO) is performed for the entire possible modes to select the optimum intra prediction mode. Fast intra mode decision methods have been introduced to reduce the number of tested modes by RDO to a few prediction modes ...

Mode activity based adaptive fast intra mode decision for HEVC/H.265

2015 8th International Congress on Image and Signal Processing (CISP), 2015
In the intra coding of HEVC/H.265, the computational complexity of intra mode decision is very high because up to 35 intra prediction modes are supported. Though a fast intra mode decision based on rough mode decision (RMD) is adopted in reference software HM12.0, only a fixed number of intra modes are selected for rate distortion optimization (RDO ...

Fast Intra Prediction Mode Decision by Adaptively Selecting Fewer Number of Modes

2007 International Conference on Machine Learning and Cybernetics, 2007
Enhanced Intra and Inter prediction techniques are the key factors to the success of H.264. There are a total of nine optional prediction modes for each 4 x 4 luma block. H.264 adapts Rate Distortion Optimization (RDO) technique to get high coding rate and visual quality.

Statistical analysis of the QTMT structure: intra mode decision

2020 IEEE 4th International Conference on Image Processing, Applications and Systems (IPAS), 2020
As part of their contribution to the continuous development of video technologies, International Telecommunication Union (ITU) and Moving Picture Experts Group (MPEG) created the Joint Expert Team (JVET) in order to study the potential need for the standardization of the future video coding, called Versatile Video Coding (VVC).

Fast selective intra mode decision in H.264/AVC

CCNC 2006. 2006 3rd IEEE Consumer Communications and Networking Conference, 2006., 2006
In this paper, we propose selective mode decision schemes for fast intra prediction mode selection. The objective is to reduce the computational complexity of the H.264/AVC encoder without significant rate-distortion performance degradation. In our proposed schemes, the intra prediction complexity is reduced by limiting the prediction modes with the ...

Fast intra-prediction mode decision for H.264/AVC

2009 ISECS International Colloquium on Computing, Communication, Control, and Management, 2009
In H.264/AVC, intra-prediction is utilized in the spatial domain. There are two types of intra prediction for luma — Intra 16×16 and Intra 4×4. Four and nine modes are supported by Intra 16×16 and Intra 4×4, respectively. The full search is used to select the best modes in H.264, which is very computationally expensive.

Fast Intra Mode Decision Algorithm for H.264/AVC

2008 Congress on Image and Signal Processing, 2008
A fast intra mode decision algorithm for H.264/AVC is proposed in this paper. The objective is to reduce the encoder complexity without significant rate-distortion performance degradation. Three methods are adopted: (1) the block size is selected between 4times4 block and 16times16 block based on the smoothness and correlation information.

A fast mode decision algorithm for HEVC intra prediction

2016 Visual Communications and Image Processing (VCIP), 2016
The latest video coding standard, High Efficiency Video Coding (HEVC) can achieve up to 50% bit rate saving while maintain the same subjective quality compared to H.264/AVC. However, this great advance is obtained at the expense of significantly increased encoder complexity. In this paper, a two-step algorithm focusing on fast mode decision is proposed

Fast Intra Prediction Mode Decision Algorithm for HEVC

2015
High Efficiency Video Coding (HEVC), which is the newest video coding standard, has significantly improved compression performance better than all the previous standards such as H.264/AVC, benefitting from more sophisticated coding technique. In the intra prediction, up to 35 prediction modes, compared to 13 prediction modes for H.264/AVC, are designed
