Task Interleaving and Orientation Estimation for High-Precision Oriented Object Detection in Aerial Images [URL][PDF][BibTex]

( accepted by ISPRS Journal of Photogrammetry and Remote Sensing).

Abstract

In this paper, we propose a Task Interleaving and Orientation Estimation Detector for high-quality oriented object detection in aerial images. Specifically, a posterior hierarchical alignment (PHA) indicator is proposed to optimize the detection pipeline. TIOE-Det adopts PHA indicator to integrate fine-grained posterior localization guidance into classification task to address the misalignment between classification and localization subtasks. Then, a balanced alignment loss is developed to solve the imbalance localization loss contribution in PHA prediction. Moreover, we propose a progressive orientation estimation (POE) strategy to approximate the orientation of objects with n-ary codes. On this basis, an angular deviation weighting strategy is proposed to achieve accurate evaluation of angle deviation in POE strategy.
