Aerial Image Object Detection With Vision Transformer Detector (ViTDet)

no code implementations28 Jan 2023 Liya Wang, Alex Tien

Our results show that ViTDet can consistently outperform its convolutional neural network counterparts on horizontal bounding box (HBB) object detection by a large margin (up to 17% on average precision) and that it achieves the competitive performance for oriented bounding box (OBB) object detection.
