摘要:

高光谱目标跟踪近年来已成为遥感领域备受关注的研究课题。高光谱图像凭借其众多波段,能够提供丰富的目标材质信息,可有效用于目标跟踪。尽管大多数高光谱跟踪器基于检测技术,但尚未有人尝试利用YOLO进行目标检测与跟踪。原因在于多光谱波段的存在、带标注的高光谱视频稀缺,以及YOLO在处理遮挡和在杂乱背景中区分目标方面的性能局限。因此,本文提出了一种名为Hy-Tracker的新型框架,旨在弥合高光谱数据与最先进目标检测方法之间的差距,从而发挥YOLOv7在高光谱视频目标跟踪中的优势。Hy-Tracker不仅引入YOLOv7,还创新性地在YOLOv7之上整合了一个精化跟踪模块。该跟踪器对YOLOv7产生的初始检测结果进行精化,从而提升目标跟踪性能。此外,我们将卡尔曼滤波器融入跟踪器,以应对尺度变化和遮挡带来的挑战。在高光谱基准数据集上的实验结果表明,Hy-Tracker能够在帧间准确跟踪目标,验证了其有效性。

英文摘要:

Hyperspectral object tracking has recently emerged as a topic of great interest in the remote sensing community. The hyperspectral image, with its many bands, provides a rich source of material information of an object that can be effectively used for object tracking. While most hyperspectral trackers are based on detection-based techniques, no one has yet attempted to employ YOLO for detecting and tracking the object. This is due to the presence of multiple spectral bands, the scarcity of annotated hyperspectral videos, and YOLO's performance limitation in managing occlusions, and distinguishing object in cluttered backgrounds. Therefore, in this paper, we propose a novel framework called Hy-Tracker, which aims to bridge the gap between hyperspectral data and state-of-the-art object detection methods to leverage the strengths of YOLOv7 for object tracking in hyperspectral videos. Hy-Tracker not only introduces YOLOv7 but also innovatively incorporates a refined tracking module on top of YOLOv7. The tracker refines the initial detections produced by YOLOv7, leading to improved object-tracking performance. Furthermore, we incorporate Kalman-Filter into the tracker, which addresses the challenges posed by scale variation and occlusion. The experimental results on hyperspectral benchmark datasets demonstrate the effectiveness of Hy-Tracker in accurately tracking objects across frames.
