SCSF-Net: Single Class Scale Fixed Network for Object Detection in Optical Remote Sensing Images on Limited Hardware

The detection of objects such as vehicle, airplane and ship is a fundamental problem in optical remote-sensing(ORS) image process. Despite a great success has achieved by migrating nature image detection methods to the remote sensing field, some challenges in hardware limit environments still remain to be solved, e.g., space-borne hardware and UAV-borne hardware. We proposed a low-computational network by digging several prior knowledge in the remote sensing field. By focusing on certain ground sample distance(gsd) and single target class, the proposed method gains high performance with only less than 1% parameters and less than 1% computation used comparing with the state-of-the-art detection method. Detection result on public available vehicle dataset demonstrates the effectiveness of the proposed method. Meanwhile, the ship and airplane detection results of two private datasets are also shown. Our vehicle detection code on limited hardware is now available at https://github.com/minghuicode/scsf-detector.
