A Fine-Grained Object Detection Framework Based on Fixed ROI Masking and Feature Optimization in Optical Remote Sensing Images

Fine-grained object detection in images aims at providing both precise positions and fine-grained categories of objects of interest, which is a challenging but meaningful task. In this paper, fine-grained object detection in optical remote sensing images is explored. To address the inefficiency of previous methods, firstly an end-to-end fine-grained detection framework with a localization branch a...
