摘要:

使用现成的和端到端训练的深度网络显着提高了RGB视频上视觉跟踪的性能。然而,缺乏大型标记数据集阻碍了卷积神经网络在热红外(TIR)图像跟踪中的使用。因此,大多数关于跟踪TIR数据的现有技术方法仍然基于手工制作的特征。为了解决这个问题,我们建议使用图像到图像的翻译模型。这些模型使我们能够将大量可用的标记RGB数据转换为合成TIR数据。我们探讨了配对和不配对的图像翻译模型的使用。这些方法为我们提供了一个大的合成TIR序列的标记数据集,我们可以训练端到端的跟踪最佳功能。据我们所知,我们是第一个训练TIR跟踪端到端功能的公司。我们在VOT-TIR 2017数据集上进行了广泛的实验。我们表明,在合成TIR数据的大数据集上训练的网络比在可用的真实TIR数据上训练的网络获得更好的性能。将两种数据源结合起来,可以进一步改进。此外,当我们将网络与运动特征相结合时,我们的表现优于最先进的技术,相对增益超过10%,清楚地表明了使用合成数据来训练端到端TIR跟踪器的效率。

英文摘要:

The usage of both off-the-shelf and end-to-end trained deep networks have significantly improved performance of visual tracking on RGB videos. However, the lack of large labeled datasets hampers the usage of convolutional neural networks for tracking in thermal infrared (TIR) images. Therefore, most state of the art methods on tracking for TIR data are still based on handcrafted features. To address this problem, we propose to use image-to-image translation models. These models allow us to translate the abundantly available labeled RGB data to synthetic TIR data. We explore both the usage of paired and unpaired image translation models for this purpose. These methods provide us with a large labeled dataset of synthetic TIR sequences, on which we can train end-to-end optimal features for tracking. To the best of our knowledge we are the first to train end-to-end features for TIR tracking. We perform extensive experiments on VOT-TIR2017 dataset. We show that a network trained on a large dataset of synthetic TIR data obtains better performance than one trained on the available real TIR data. Combining both data sources leads to further improvement. In addition, when we combine the network with motion features we outperform the state of the art with a relative gain of over 10%, clearly showing the efficiency of using synthetic data to train end-to-end TIR trackers.
