This is the journal version of our previous work. We make three changes: (1) We have extended the original multi-frame validation strategy. (2) We utilize an entropy-based image patch selection and HOG-based KCF tracker for data-preprocessing. (3) We visualized and analyzed the unsupervised feature representations. We have conducted more experiments on VOT2017/2018, LaSOT, and TrackingNet to justify our tracker.

Abstract

We propose an unsupervised visual tracking method in this paper. Different from existing approaches using extensive annotated data for supervised learning, our model is trained on large-scale unlabeled videos in an unsupervised manner. Our motivation is that a robust tracker should be effective in both the forward and backward ways, i.e., the tracker can forward localize the target object in successive frames and backtrace to its initial position in the first frame. We build our method on a Siamese correlation filter network, which is trained using raw videos without labels. Meanwhile, we propose a multiple-frame validation and a cost-sensitive loss to further facilitate the unsupervised learning. Without bells and whistles, our unsupervised tracker achieves the baseline accuracy of fully-supervised trackers, which require complete and accurate labels for training. Furthermore, unsupervised framework exhibits potential in leveraging unlabeled or weakly labeled data to further improve the tracking accuracy.

Usage

Requirements: Matlab and MatConvNet.

Before running the code, you need to compile the matconvnet first.

For training and testing, please refer to the readme.md in the corresponding folder.
