EventAnchor: Reducing Human Interactions in Event Annotation of Racket Sports Videos

no code implementations13 Jan 2021 Dazhen Deng, Jiang Wu, Jiachen Wang, Yihong Wu, Xiao Xie, Zheng Zhou, HUI ZHANG, Xiaolong Zhang, Yingcai Wu

The popularity of racket sports (e. g., tennis and table tennis) leads to high demands for data analysis, such as notational analysis, on player performance.

Parallel ensemble methods for causal direction inference

no code implementations5 Jun 2020 Yulai Zhang, Jiachen Wang, Gang Cen, Guiming Luo

Inferring the causal direction between two variables from their observation data is one of the most fundamental and challenging topics in data science.

Fully Automatic Liver Attenuation Estimation Combing CNN Segmentation and Morphological Operations

1 code implementation23 Jun 2019 Yuankai Huo, James G. Terry, Jiachen Wang, Sangeeta Nair, Thomas A. Lasko, Barry I. Freedman, J. Jeffery Carr, Bennett A. Landman

Manually tracing regions of interest (ROIs) within the liver is the de facto standard method for measuring liver attenuation on computed tomography (CT) in diagnosing nonalcoholic fatty liver disease (NAFLD).
