Abstract

Electronic devices are deeply entrenched in our daily lives and are used so much that they take up most of our time. Using these electronic devices to judge a person's psychological state and give feedback appropriate to the situation can help a lot in life. A method using CNN has been studied as an existing facial emotion classification technique, but this method has the disadvantage that it requires a lot of training data because it receives tens of thousands of pixels as input data. In this paper, to solve this problem, we propose a deep learning model DFLM (Deeplearning facial landmark model) that receives facial landmarks as input data and classifies facial emotions. The proposed DFLM can classify 7 facial expressions by constructing a fully connected neural network with 68 landmarks as inputs. As a result of the simulation, it is possible to learn faster than a CNN model, and its operation time is short, so it will be helpful in areas that need to make predictions in real time.
