How to Detect Emotions in Images using Python

One of the easiest, and yet also the most effective, ways of analyzing how people feel is looking at their facial expressions. Most of the time, our face best describes how we feel in a particular moment. This means that emotion recognition is a simple multiclass classification problem. We need to analyze a person's face and put it in a particular class, where each class represents a particular emotion. In Python, we can use the DeepFace and FER libraries to detect emotions in images.
