Researchers have developed a new weakly supervised framework for detecting schools from aerial imagery, designed to function effectively in low-data environments. This method utilizes an automatic labeling pipeline that generates bounding boxes from sparse location points and semantic segmentation masks. The approach involves a two-stage training process: first pretraining on automatically labeled data, then fine-tuning with a small set of manually annotated images, significantly reducing the need for extensive manual labeling.
