Ji Fan is a graduate student in the Department of Software Engineering at Northwestern Polytechnical University. He received his Bachelor’s degree in Software Engineering from Northwestern Polytechnical University in 2019. He has been studying for a master’s degree in the Department of software engineering, Northwestern Polytechnical University since 2019. His research interests include image processing, pose estimation and action recognition, etc. He has been studying the action recognition of basketball players based on computer vision since 2019. His undergraduate thesis is about player’s pose recognition based on OpenPose in multi-view videos. It is to extract the 3D key points of the human body in the images taken by multiple RGB cameras with openpose, and then use a decision tree and random forest to identify the player’s action.
