A Novel Apex-Time Network for Cross-Dataset Micro-Expression Recognition

1 code implementation7 Apr 2019 Min Peng, Chongyang Wang, Tao Bi, Tong Chen, Xiangdong Zhou, Yu Shi

As researchers working on such topics are moving to learn from the nature of micro-expression, the practice of using deep learning techniques has evolved from processing the entire video clip of micro-expression to the recognition on apex frame.
