Detecting and recognizing the emotions of a person based upon the facial expressions produced by them. Usually, one has a talk with a person to know about his/her emotions or mental state. But, it seems uncomfortable for one to talk about his/her mental health. So, instead of asking a person directly to talk about it, a tool is designed which can read the emotions by using the facial expressions. This paper helps to make an inference about the mental health of a person using the primary categories of emotions which are happiness, sadness, anger, surprise, fear and disgust. The proposed tool can be used at various places such as hospitals (to read a patient’s expressions), at airports (to detect suspicious facial expressions), in schools/colleges (to analyze the mood of students), etc. For example, teenagers who might be facing difficulties with their studies/social life tend to have a mental imbalance after long time of battling with their own emotions. Unfortunately, they ultimately become mentally weak and enter into a mental state generally called depression. They might take a wrong step to take their own life and end up into an unfortunate incident for the society. If the emotions of such teenagers are read using this tool in the early stages of struggling, it might help the society to help them get out of their situation.
