论文摘要
尽管短期完全阻塞在视觉对象跟踪中很少发生，但在这种情况下，大多数跟踪器都会失败。但是，人类仍然可以通过预期目标的轨迹来赶上目标，甚至目标是看不见的。最近的心理学还表明，人类建立了未来的心理形象。受此启发的启发，我们提出了一个幻觉功能，可以跟踪（HAFT）模型，该功能可以预测未来框架的视觉功能嵌入。预期的未来框架着眼于目标的运动，同时幻觉了目标的阻塞部分。在幻觉功能上共同跟踪和真实功能可以提高跟踪器的鲁棒性，即使目标被高度遮住。通过广泛的实验评估，我们在多个数据集上实现了有希望的结果：OTB100，DOCT2018，LASOT，TRACKINGNET和UAV123。
Although short-term fully occlusion happens rare in visual object tracking, most trackers will fail under these circumstances. However, humans can still catch up the target by anticipating the trajectory of the target even the target is invisible. Recent psychology also has shown that humans build the mental image of the future. Inspired by that, we present a HAllucinating Features to Track (HAFT) model that enables to forecast the visual feature embedding of future frames. The anticipated future frames focus on the movement of the target while hallucinating the occluded part of the target. Jointly tracking on the hallucinated features and the real features improves the robustness of the tracker even when the target is highly occluded. Through extensive experimental evaluations, we achieve promising results on multiple datasets: OTB100, VOT2018, LaSOT, TrackingNet, and UAV123.
