Micro-expressions,as the name suggests,are short termed facial expressions lasting only for a fraction of seconds. They usually occur when a person either knowingly or unknowingly tries to conceal his feelings or emotions. Detection of these expressions has proven to be useful in detecting a person's mood and his real intentions. Some recent studies indicate that some leaked facial micro-expressions occuring for a very short duration of about 1/25 to 1/3 seconds can't be faked. In order to detect such expressions a high speed camera with a frame rate of 100fps or higher is required. In this paper,various techniques used for micro-expression recognition have been analysed. Pros and cons of these techniques have also been discussed alongwith their future scope.
