Abstract: An important issue of the emotional recognition, the Micro-expression recognition has received very long attention and fast development in past one decade. In the paper, our own selves give a view of the growth of the in recognition of Micro-expression. This elaborate various feature extraction methods, various classification techniques and various databases were discussed which are used to estimate the Micro-expression. In the conclusion, we discuss existing research challenges in the Micro-expression to enhance the recognition rate.
Keyword: Facial Micro-expression, Feature extraction.
