Abstract

Convolutional Neural Networks are a popular approach for image classification problem. This article presents an overview of open-source facial expression datasets and performance comparison of CNN models. Evaluated model, trained to detect seven basic emotions, on the combined set of datasets offers 86,7% of accuracy on a validation set and 97,2% on a training set. In this work a system of automated appropriate response to human emotion expression and set of layers that ensure high performance are proposed. The system combines real-time CNN with robotic head OhBot. The information about current emotional state of a person based on its facial expression is the input signal for the subsystem controlling the robotic head, whose task is to react appropriate to the situation.
