Abstract
En 中文
Existing deep trackers can be roughly divided into either matching-based or classification-based methods. The formers are fast but not very robust; while the latter ones introduce more discriminative information but often very slow. In this work, we present a novel real-time robust tracking method to take full use of the benefits from both kinds of networks. First, we propose a matching-classification network switching (MCS) framework to integrate the matching, classification, verification networks and conduct dynamic switching among them. Second, to speed up online update, we devlop a meta learning method as a critical component in our classification network. The meta classifier is trained offline to obtain general discriminative ability and updated online to the current frame just through one iteration. Extensive experiments are conducted on two popular benchmark datasets. Both qualitative and quantitative evaluations show that our tracker performs favorably against other state-of-the-art trackers with real-time performance. (C) 2020 Published by Elsevier Ltd.
