Rifat Bin Yusuf; Labib Rahman; Dr. Shazzad Hosain; 1931672042; 1931857042; 1912217042; 1931740042Facial emotion recognition is an important research area with various applications such as human-computer interaction, psychology and social robotics. Consequently, there has been active research in the field using the approach of Convolutional Neural Networks (CNNs), for feature extraction and inference. In our paper, we explored the use of Bag of Visual Words(BoVW) and CNNs on the FER2013 dataset without any additional training data. To combine the features from both methods, we concatenated the feature vectors obtained from BoVW and CNN. Subsequently, we employed a Support Vector Machine (SVM) classifier to train and classify the concatenated feature vectors. The evaluation of our approach on the FER2013 dataset yielded an accuracy of 62%. Although this accuracy level indicates room for improvement, it demonstrates the potential of utilizing both BoVW and CNN in facial emotion recognition tasks. Overall, this study showcases the effectiveness of combining the BoVW approach with CNN for facial emotion recognition. The results obtained serve as a foundation for further investigations and advancements in this field.
