CU Partition Mode Decision for HEVC Hardwired Intra Encoder Using Convolution Neural Network
TL;DR: The convolution neural network based fast algorithm is devised to decrease no less than two CU partition modes in each CTU for full rate-distortion optimization (RDO) processing, thereby reducing the encoder's hardware complexity.

Pseudo-sequence-based light field image compression
TL;DR: Experimental results show the superior performance of the pseudo-sequence-based scheme, which achieves as high as 6.6 dB gain compared with directly encoding the raw image by the legacy JPEG.
Journal ArticleDOI
Laplace Distribution Based Lagrangian Rate Distortion Optimization for Hybrid Video Coding
TL;DR: The proposed Lap-lambda is able to adaptively optimize the input sequences so that the overall coding efficiency is improved, and compared with HR-lambda, shows a much better or similar performance in all scenarios.

A Fast CU Size Decision Algorithm for the HEVC Intra Encoder
Biao Min,Ray C. C. Cheung +1 more
TL;DR: A novel fast algorithm is proposed for the CU size decision in intra coding using the global and local edge complexities in horizontal, vertical, 45° diagonal, and 135° diagonal directions to decide the partitioning of a CU.

Histogram-Based Prefiltering for Luminance and Chrominance Compensation of Multiview Video
TL;DR: The usage of histogram matching prior to multiview encoding leads to substantial gains in the coding efficiency, and this prefiltering step can be combined with block-based illumination compensation techniques that modify the coder and decoder themselves, especially with the approach implemented in the Multiview reference software of the joint video team (JVT).
