Recognition training of fleeting involuntary facial expressions often known as micro expressions. These expressions can be extremely accurate in portraying concealed emotion, yet often go unnoticed due to their extremely short duration (1/25 - 1/15 second).

Please bear in mind information within this project is as yet unverified. We are continually working to increase accuracy and improve expression images. More faces will be added early 2018
