Facial Expression conveys non - verbal cues, which plays an important role in interpersonal relations. The Facial Expression Recognition system is the process of identifying the emotional state of a person. In this system captured image is compared with the trained dataset available in database and then emotional state of the image will be displayed. A face recognition system is one of the biometric information processes its applicability is easier and working range is larger than others, i. e., Fingerprint, iris scanning, signature etc. An algorithm that performs detection, extraction, and evaluation of these facial expressions will allow for automatic recognition of human emotion in images and videos.
