Linqin Cai, Hao Li, Wei Dong, Haodu Fang

Abstract: Highlights•Appropriate preprocessing promotes the extraction of micro-expression features.•The three-dimensional DenseNet can extract facial features deeply.•SE block combined with DenseNet can facilitate feature extraction.•Different SE block combination methods significantly affect the recognition rate.
