A weighted feature extraction method based on temporal accumulation of optical flow for micro-expression recognition

作者：

Highlights：

• We proposed a feature extraction method based on temporal accumulated optical flow.

• The temporal accumulated optical flows reduce the displacements of image noises.

• The proposed method improves the performance of micro-expression recognition.
