Spontaneous subtle expression detection and recognition based on facial strain

作者：

Highlights：

• The method proposed is a combination of two optical strain derived features.

• Optical strain magnitudes were employed to describe fine subtle facial movements.

• Evaluation was performed in both the detection and recognition tasks.

• Promising performances were obtained in two micro-expression databases.
