Multi-task mid-level feature learning for micro-expression recognition

作者：

Highlights：

• A multi-task mid-level feature learning framework was proposed to improve the discrimination ability of low-level features.

• A new micro-expression database captured by mobile devices was collected.

• Extensive experiments are conducted to illustrate that our method can improve the performance of existing low-level features.
