UniKF, a Kalman-filter-based late fusion for BEV detections, achieves lower errors than IoU-based baselines on synthetic noise, but only marginal gains over the authors' own WLS method.

abstract
In this report, we introduce the technical details of our submission to the VIPriors object detection challenge. Our solution is based on mmdetction of a strong baseline open-source detection toolbox. Firstly, we introduce an effective data augmentation method to address the lack of data problem, which contains bbox-jitter, grid-mask, and mix-up. Secondly, we present a robust region of interest (ROI) extraction method to learn more significant ROI features via embedding global context features. Thirdly, we propose a multi-model integration strategy to refinement the prediction box, which weighted boxes fusion (WBF). Experimental results demonstrate that our approach can significantly improve the average precision (AP) of object detection on the subset of the COCO2017 dataset.

Evaluation of an Uncertainty-Aware Late Fusion Algorithm for Multi-Source Bird's Eye View Detections Under Controlled Noise
UniKF, a Kalman-filter-based late fusion for BEV detections, achieves lower errors than IoU-based baselines on synthetic noise, but only marginal gains over the authors' own WLS method.
