A Facial Expression Is Worth a Thousand Words

[...] Scientists from the Max Planck Institute for Biological Cybernetics in Tübingen, Germany, found out that we are able to recognize facial expressions in motion -- for example, in a movie -- far better than in a static photograph. The video sequence needs to be at least as long as one tenth of a second to gain this dynamic advantage.

Interpreting this facial expression correctly (as a "baffled" expression) is very difficult based on this photo alone. When showing the corresponding video sequence, however, recognition becomes easy, which underlines the importance of the temporal dimension for effective communication.

Face Video DatabaseThis database ontains videos of facial action units taken from 6 different
camera views from one actor. Facial action units are basic muscle movements that have been proposed to underlie the production of facial expressions.
