This project presents an innovative approach to stress detection by utilizing Convolutional Neural Networks (CNNs) to analyze emotional cues extracted from facial images. The proposed system employs CNNs, a class of deep learning models known for their efficacy in image recognition tasks, to automatically extract features from facial images. Through a combination of convolutional, pooling, and fully connected layers, the CNN learns hierarchical representations of facial expressions associated with various emotions, including those indicative of stress. The model is trained on a diverse dataset encompassing a wide range of facial expressions, allowing it to generalize well to unseen data. Transfer learning techniques may also be employed to leverage pre-trained CNN models, further enhancing performance with limited data.
