Efficient Fast Intra Mode Decision using Transform Coefficients

The 9th International Conference on Advanced Communication Technology, 2007
The H.264/AVC standard substantially improved its coding efficiency and subjective quality by using the intra prediction technique and the adaptive coding between inter and intra modes based on rate-distortion optimization. This encoding scheme, however, increases encoding complexity dramatically and causes troubles in its practical applications in the

Efficient Intra Mode Decision Via Statistical Learning

2007
Intra mode selection and motion estimation for spatial and temporal prediction play important roles for achieving high video compression ratio in the latest video coding standards, such as H.264/AVC. However, both components take most of the computational cost in the video encoding process.

A fast intra mode decision algorithm for AVS

IEEE 10th INTERNATIONAL CONFERENCE ON SIGNAL PROCESSING PROCEEDINGS, 2010
The AVS video coding standard employs a robust Rate-Distortion Optimization (RDO) technique to improve compression performance. Although RDO technique can achieve better compression efficiency, it also increases tremendous computational complexity. In order to reduce complexity, this paper proposes a fast intra mode decision algorithm for AVS based on ...

Fast intra mode decision for depth map coding

2013 IEEE International Symposium on Consumer Electronics (ISCE), 2013
Nowadays, JCT-3V joined by ITU-T VCEG and ISO/IEC MPEG is developing new 3D video coding standard, MVC+D and 3D-AVC, based on H.264/AVC. In addition to color image, depth map is also included to be compressed because of adopting DIBR to generate virtual views.

CNN oriented fast HEVC intra CU mode decision

2016 IEEE International Symposium on Circuits and Systems (ISCAS), 2016
The real-time requirements of hardwired HEVC encoder demand that, at the grain of coding tree unit (CTU), the maximum computation should be reduced by a fast CU mode decision algorithm. In addition, to realize the parallel rate-distortion optimization (RDO) of different CU modes, the current CU mode decision should not use the auxiliary information ...

Edge information based effective intra mode decision algorithm

2012 IEEE International Conference on Signal Processing, Communication and Computing (ICSPCC 2012), 2012
In this paper, we present very simple, yet efficient, algorithms for intra mode decision algorithms in AVS video coding based on edges detection and neural network. The technique uses the SOBEL operator to check the edge information from the total image before its intra prediction.

An adaptive fast intra mode decision in HEVC

2012 19th IEEE International Conference on Image Processing, 2012
Compared with H.264/AVC, the emerging video coding standard, High Efficiency Video Coding (HEVC), introduces a lots of intra prediction modes in intra coding, which brings a real challenge in practice. Although the Rough Mode Decision (RMD) scheme in HEVC provides a fast mode decision, it is a fixed strategy for different blocks with the same size and ...

Simplified Directional Mode Selection for H.264/AVC Intra Mode Decision

2010 International Conference on Computational Intelligence and Software Engineering, 2010
Fast mode decision for intra mode prediction in H.264/AVC trades off between rate distortion performance and encoding complexity. Edge direction method has been certified available by reducing unlikely orientation features which are represented by eight values derived from pixel-value processing. In this paper, we proposed a new method to simplify this
