Emotion Detection using Facial Expressions

Emotional Expressions gives us much-needed details about a person's feelings and sentiment. Geometry and appearance are the main base of the FER system. With the advancement in machine learning, it has become possible to detect emotions from voice, text, and pictures. As of now, extensive advanced machines are utilizing emotion recognition to make their communication better with humans. Facial Expression Recognition (FER) mainly depends on deep learning models trained with comprehensive datasets. We have used the supervised feature selection technique to decrease the dataset's size. This paper supplies us with a comparative analysis of numerous tactics and algorithms which have been studied for sensing different human facial expressions. The study implements extensive forms of surveys and research work done by different scholars and researchers which focuses on many outlooks recognized in emotion detection.
