Highly Efficient Anchor-Free Oriented Small Object Detection for Remote Sensing Images via Periodic Pseudo-Domain

Abstract: With the continuous progress of remote sensing image object detection tasks in recent years, researchers in this field have gradually shifted the focus of their research from horizontal object detection to the study of object detection in arbitrary directions. It is worth noting that some properties are different from horizontal object detection during oriented object detection that researchers have yet to notice much. This article presents the design of a straightforward and efficient arbitrary-oriented detec… Show more

“…Ref. [36] proposed ratio-balanced angle loss, enabling better balance between low and high-aspect ratio objects, avoiding redundant designs, and enhancing small object detection quality. Despite its effectiveness in handling small objects with varying aspect ratios, this method may be susceptible to background noise in complex environments, potentially increasing false detections.…”
