Active-SAOOD: Active Sparsely Annotated Oriented Object Detection in Remote Sensing Images
Researchers have developed Active-SAOOD, a novel method to reduce the cost of annotating oriented objects in remote sensing images. This active learning approach intelligently selects the most informative sparse samples for annotation, considering factors like orientation, classification, and localization uncertainty. Experiments show Active-SAOOD significantly boosts performance and stability, achieving a 9% gain with only 1% of data annotated. AI
IMPACT Reduces annotation costs for object detection in remote sensing, potentially accelerating development and deployment of AI systems in this domain.
