In this project, we use the active fire dataset from https://github.com/pereira-gha/activefire (data link) and try to improve over their results. We use two Vision Transformer networks: Swin-Unet and TransUnet, and one CNN-based UNet network. We show that ViT can outperform well-trained and specialized CNNs to detect wildfires on a previously published dataset of LandSat-8 imagery (Pereira et al.). One of our ViTs outperforms the baseline CNN comparison by 0.92%. However, we find our own implementation of CNN-based UNet to perform best in every category, showing their sustained utility in image tasks. Overall, ViTs are comparably capable in detecting wildfires as CNNs, though well-tuned CNNs are still the best technique for detecting wildfire with our UNet providing an IoU of 93.58%, better than the baseline UNet by some 4.58%.

• UNet.py: Contains the pytorch code for UNet model.
• evaluate.py: Takes in the model name and evaluates the saved checkpoint on 4 metrics: precision, recall, f-score, and IoU.
• generator.py: Data generator code.
• models.py: Returns the instances of different models used in this work.
• predict.py: Saves the inference result from the a checkpoint file.
• train.py: Code to train a model.
• transform.py: Image transforms for data augmentation.
