Model description
The vit-face-expression model is a Vision Transformer fine-tuned for the task of facial emotion recognition.
It is trained on the FER2013 and MMI facial Expression datasets , which consist of facial images categorized into seven different emotions:
- Angry
- Disgust
- Fear
- Happy
- Sad
- Surprise
- Neutral
Data Preprocessing
The input images are preprocessed before being fed into the model. The preprocessing steps include:
- Resizing: Images are resized to the specified input size.
- Normalization: Pixel values are normalized to a specific range.
- Data Augmentation: Random transformations such as rotations, flips, and zooms are applied to augment the training dataset.
