[Article] CAS(ME)3: A third generation facial spontaneous micro-expression database with depth information and high ecological validity.

summary : Recently, Micro-Expression(ME) is one of the popular research interest for Facial Expression Recognition(FER) task. In particular, depth information is often utilized to analyze micro expressions. CAS(ME)3 offers around 80 hours of video dataset with manually labelled micro-expressions & macro-expressions. They also provide depth information and demonstrate effective way to process depth information for multimodal Mircro Expression Recognition(MER). CAS(ME)3 is currently one of the most well-known RGB-D dataset for emotion recognition.
