A Study on Emotion Recognition Method and Its Application using Face Image

In this paper, we introduce seven emotions and positive and negative emotion recognition methods using facial images and the development of apps based on the method. In previous researches, they used the deep-learning technology to generate models with emotion-based facial expressions to recognized emotions. There are existing apps that express six emotions, but not seven emotions and positive and negatives in graphs and percentages. Thus, we recognized seven emotions such as Angry, Disgust, Fear, Happy, Sad, Surprise, and Neutral and also classified the calculated emotion-recognition scores into positive, negative and neutral emotions. Then we implemented an app that provides the user with seven emotions scored and positive and negative emotions.
