论文摘要
无人机（UAV）跟踪在农业，导航和公共安全等中具有广泛的潜在应用。但是，计算资源，电池容量和无人机的最大负载的局限性阻碍了无人机上基于深度学习的跟踪算法的部署。因此，由于它们的效率很高，因此在UAV跟踪社区中脱颖而出的判别相关过滤器（DCF）跟踪器脱颖而出。但是，它们的精度通常比基于深度学习的跟踪器要低得多。模型压缩是一种有希望的方法，可以缩小基于DCF和深度学习的跟踪器之间差距（即效率，精度），这并没有引起无人机跟踪中的太多关注。在本文中，我们提出了P-SIAMFC ++跟踪器，该跟踪器是第一个使用基于等级的过滤器修剪来压缩SIAMFC ++模型的方法，在效率和精度之间取得了显着的平衡。我们的方法是一般的，可以鼓励通过模型压缩对无人机跟踪的进一步研究。在四个无人机基准测试中进行的广泛实验，包括UAV123@10FPS，DTB70，UAVDT和Vistrone2018，表明P-SiAMFC ++跟踪器显着胜过最先进的无人机跟踪方法。
Unmanned aerial vehicle (UAV) tracking has wide potential applications in such as agriculture, navigation, and public security. However, the limitations of computing resources, battery capacity, and maximum load of UAV hinder the deployment of deep learning-based tracking algorithms on UAV. Consequently, discriminative correlation filters (DCF) trackers stand out in the UAV tracking community because of their high efficiency. However, their precision is usually much lower than trackers based on deep learning. Model compression is a promising way to narrow the gap (i.e., effciency, precision) between DCF- and deep learning- based trackers, which has not caught much attention in UAV tracking. In this paper, we propose the P-SiamFC++ tracker, which is the first to use rank-based filter pruning to compress the SiamFC++ model, achieving a remarkable balance between efficiency and precision. Our method is general and may encourage further studies on UAV tracking with model compression. Extensive experiments on four UAV benchmarks, including UAV123@10fps, DTB70, UAVDT and Vistrone2018, show that P-SiamFC++ tracker significantly outperforms state-of-the-art UAV tracking methods.
