In human life, facial expressions and emotions reveal external and internal responses. In human-computer interaction, the video clip plays an important part for extract the emotion of the end-user. In this type of system, it is necessary to observe rapid dynamic changes in the motion of the human face to give the essential response. A real-time application is based on identifying the face and recognizes his expressions such as happy, sad, disgruntled and tiredness, etc. for example Driver exhaustion detection to prevent road accidents on the road. We focus on the comprehensive study of different traditional and recent methodsfor preprocessing, features take out and emotion recognition is employed in facial expression and recognition systems (FER). This paper also describes various Terminologies are used in the Facial expression and recognition system (FER) system. The result compares with the Number of Expressions, algorithm accuracy, and implementation tools. Video-based facial emotion recognition is a very interesting and challenging problem hence the present study provides model complexity, implementation trends, and opportunities for researchers can consider as future research works.
