Description

The CASME II database (http://fu.psych.ac.cn/CASME/casme2-en.php) has the following characteristics:

  • The samples are spontaneous and dynamic micro-expressions. Baseline (usually neutral) frames are kept before and after each micro-expression, making it possible to evaluate different detection algorithms.
  • The recordings have high temporal resolution (200 fps) and relatively higher face resolution at 280x340 pixels.
  • Micro-expression labeling is based on FACS investigator's guide and Yan et al. findings (Yan et al., 2013) that is different from the traditional 6 categories on ordinary facial expression.
  • The recordings have proper illumination without lighting flickers and with reduced highlight regions of the face.
  • Some types of facial expressions are difficult to elicit in laboratory situations, thus the samples in different categories distributed unequally, e.g., there are 60 disgust samples but only 7 sadness samples. In CASME II, we provide 5 classes of micro-expressions.
