- Abstract
Deep learning has been widely used in many visual recognition tasks owing to its powerful representation ability. However, online learning is a bottleneck to obstruct the application of deep learning in visual tracking. Although many algorithms have discarded the process of online learning during tracking, they demonstrate poor robustness to the online adaptation to appearance changes of the target. In this study, the authors design a tree structure specifically for online learning, which enables the appearance model to be updated smoothly. Once the target appearance has changed severely, a new branch is generated to avoid the fuzzy boundary of classification. In addition, active learning technique and artificial data are employed in the update to make the best of the limited knowledge about the interesting object during the tracking process. The proposed algorithm is evaluated on OTB2013 and VOT2017 benchmark and outperforms many state‐of‐the‐art methods.
