Researchers from the University of Science and Technology of China and Tencent AI Lab developed an unsupervised deep tracking (UDT) framework that trains Convolutional Neural Networks for visual tracking exclusively using unlabeled video data. The method leverages forward-backward trajectory consistency as a self-supervisory signal, achieving performance comparable to supervised baselines and even some state-of-the-art trackers when enhanced with advanced online updates, thereby reducing reliance on costly manual annotations.
Key insights
- Forward-backward trajectory consistency provides an effective self-supervisory signal for learning deep features specifically optimized for visual tracking from unlabeled data.
- Learning generalizable tracking features can be achieved by training on randomly initialized bounding box regions in unlabeled videos, rather than relying on complete, pre-defined object instances.
- Robust unsupervised training for tracking requires strategies to mitigate noisy self-supervisory signals, such as multi-frame validation and cost-sensitive weighting, to focus on informative samples.
