Small object detection and counting in aerial images are active research and development areas and have many real applications. Monitoring waterfowl populations is essential for wildlife conservation in Missouri. This project aims at developing deep-learning based methods for small object (e.g., birds, people, animals, etc.) detection and counting in aerial images taken by drones or unmanned aircraft systems (UAS). The majority of the deep learning methods for object detection have been developed for large objects, and their performances on small-object detection are not as good. State-of-the-art deep learning methods for object detection are evaluated using a Little Birds in Aerial Imagery (LBAI) dataset, created from real-life aerial imagery data. They include object detection techniques YOLOv2, SSH, and Tiny Face, and small instance segmentation techniques U-Net and Mask R-CNN. SSH performed the best for easy cases, whereas Tiny Face performed the best for hard cases, where a cluttered background makes detecting birds difficult.
