Researchers investigated the effectiveness of five different deep learning architectures, including YOLOv11, Mask R-CNN, DeepLabv3, Swin-UNet, and DINOv2, for tree canopy segmentation using a very limited dataset of only 150 images. Their findings indicate that pretrained convolutional neural network models, specifically YOLOv11 and Mask R-CNN, demonstrated superior generalization compared to transformer-based models in this low-data scenario. The study suggests that transformer architectures struggle with extreme data scarcity without extensive pretraining or augmentation, and highlights the continued reliability of lightweight CNNs for tasks with limited imagery.
