## 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.
