Longlong Jing

I am a fifth year Ph.D. student in the Media Lab, Dept. Electrical Engineering at The City College of New York, CUNY, advised by Professor Ying-Li Tian. My current research focuses on Video Analysis including human action recognition and self-supervised video feature learning. Prior to CUNY, I finished my Bachelor's degree from Central South University.

Research

I am interested in computer vision, machine learning, and image processing. Most of my research is about video analysis such as human action recognition, video feature self-supervised learning, and video feature learning from noisy data. I have also worked in weakly supervised semantic segmentation and lung nodule segmentation in CT scans with Generative Adversarial Networks.
