In this era of technology, we need applications which could be easy to use and are user-friendly that even people with certain disabilities could use them easily. Many applications exist for human behavior understanding, detection of mental disorders, and synthetic human expressions in the domain of automatic facial recognition systems. Generally, most of the publications propose two methods for automatic Facial Expression Recognition (FER) systems i.e. geometric based and appearance based

While facial expressions are naturally dynamic, they are not easy to detect so the focus of the study is now shifted to find new methods which would be helpful to improve accuracy, lower computational cost, and less memory consumption. This paper demonstrates a quick survey of facial expression recognition by analyzing various algorithms; evaluated by comparing their results in general which in turn broadened the scope for other researchers they could efficiently offer a solution to related problems.
