The human face is main part to recognize the individuals as well as provides the important information, current state of user behavior through their different expressions.Therefore, in biometric area of the research, automatically face & face expression recognition attracts researcher's interest.The other areas which use such technique are computer science medicine, psychology etc. Usually face recognition system is consisting of many internal tasks.Face detection is thefirst task of such systems.Due to different variations across the human faces, the process of detecting face becomes complex.But with help of different modeling methods, it becomes possible to recognize the face and hence different face expressions.This paperpresents a literature review over the techniques and methods used for facial expression recognition.Also, different facial expression datasets available for the research or testing of existing methods of facial expression recognition are discussed.
