Human Pose Estimation using Global and Local Normalization
Ke Sun, Cuiling Lan, Junliang Xing +3
In this paper, we address the problem of estimating the positions of human joints, i.e., articulated pose estimation. Recent state-of-the-art solutions model two key issues, joint…
Neural network-based arithmetic coding of intra prediction modes in HEVC
Rui Song, Dong Liu, Houqiang Li +1
In both H.264 and HEVC, context-adaptive binary arithmetic coding (CABAC) is adopted as the entropy coding method. CABAC relies on manually designed binarization processes as well…
229 nm UV LEDs using p-type silicon for increased hole injection
Dong Liu, Sang June Cho, Jeongpil Park +10
Ultraviolet (UV) light emission at 229 nm wavelength from diode structures based on AlN/Al0.77Ga0.23N quantum wells and using p-type Si to significantly increase hole injection was…
Laser Streaming: Turning a Laser Beam into a Flow of Liquid
Yanan Wang, Qiuhui Zhang, Zhuan Zhu +9
Transforming a laser beam into a mass flow has been a challenge both scientifically and technologically. Here we report the discovery of a new optofluidics principle and demonstrat…
UVC LEDs on Bulk AlN Substrates Using Silicon Nanomembranes for Efficient Hole Injection
Sang June Cho, Dong Liu, Jung-Hun Seo +12
As UV LEDs are explored at shorter wavelengths (< 280 nm) into the UVC spectral range, the crystalline quality of epitaxial AlGaN films with high Al compositions and inefficient ho…
Visual Analyses of Music History: A User-Centric Approach
Jingxian Zhang, Dong Liu
Music history, referring to the records of users' listening or downloading history in online music services, is the primary source for music service providers to analyze users' pre…
A Convolutional Neural Network Approach for Half-Pel Interpolation in Video Coding
Ning Yan, Dong Liu, Houqiang Li +1
Motion compensation is a fundamental technology in video coding to remove the temporal redundancy between video frames. To further improve the coding efficiency, sub-pel motion com…
An Efficient Four-Parameter Affine Motion Model for Video Coding
Li Li, Houqiang Li, Dong Liu +4
In this paper, we study a simplified affine motion model based coding framework to overcome the limitation of translational motion model and maintain low computational complexity.…
Convolutional Neural Network-Based Block Up-sampling for Intra Frame Coding
Yue Li, Dong Liu, Houqiang Li +4
Inspired by the recent advances of image super-resolution using convolutional neural network (CNN), we propose a CNN-based block up-sampling scheme for intra frame coding. A block…
