A comparative study on facial expression recognition using local binary patterns, convolutional neural network and frequency neural network

As the principal processing method for nonverbal intentions, Facial Expression Recognition (FER) is an important and promising topic of computer vision and artificial intelligence, as well as one of the subject areas of symmetry. This research work provides a thorough and well-organized comprehensive comparative empirical study of facial expression recognition based on a deep learning study in frequency domain, convolution neural network, and local binary patterns features. We have attained the FER by incorporating neutral, joy, anger, fear, sadness, disgust, and surprise as seven universal emotional categories. In terms of methodology, we present a broad framework for a traditional FER approach and analyze the possible technologies that can be used in each component to emphasis the contrasts and similarities. Even though there has been a lot of research done with static images, there is still a lot of work being done to develop new ways that are easier to compute and use less memory than prior methods. This research could pave the way for a new approach to facial emotion identification in terms of accuracy and high-performance.
