Here, our application introduces a Convolutional Neural Network (CNN) implemented architecture to detect the sentiment of a person using facial and visual clues. Such a system can be used to moderate content based on the sentiment of the person. This application is highly useful in modern world where we rely on video calls more and more.
Human facial expressions are an integral means of displaying sentiments. Automatic analysis of these unspoken sentiments has been an interesting and challenging task in the domain of computer vision with its applications ranging across multiple domains including psychology, product marketing, process automation etc.
This task has been a difficult one as humans differ greatly in the manner of expressing their sentiments through expressions. Previously various machine learning techniques like Random forest, SVM etc. were used to predict the sentiment using converted images.
Deep learning has been instrumental in making breakthrough progress in many fields of research including computer vision. We implement a convolutional neural network (CNN) based model for facial sentiment detection. For training and testing purposes, the FER-2013 public dataset is utilized.
