SSPNet: Scale Selection Pyramid Network for Tiny Person Detection from UAV Images
简介:
航空图像中的微小物体检测仍然是一个非常具有挑战性的问题,因为微小物体包含少量的像素,很容易与背景混淆。
为了推进航空图像中微小物体检测的研究,作者提出了一个新的航空图像中微小物体检测数据集(AI-TOD)。具体来说,AI-TOD拥有280,36张航空图像中8个类别的700,621个物体实例。
与现有的航空图像目标检测数据集相比,AI-TOD中的目标平均大小约为12.8像素,比其他图像要小得多。

为了建立一个在航空图像中的微小物体检测的基准,作者还在AI-TOD数据集上评估了最先进的目标检测器。
实验结果表明,将这些方法直接应用于AI-TOD会产生次优目标检测结果,因此需要设计新的微型目标检测器。
因此,作者提出了一种基于多中心点的学习网络(M-CenterNet)来提高小目标检测的定位性能,实验结果表明,该性能提高显著。
