ReTracker: Exploring Image Matching for Robust Online Any Point Tracking

Figure 1. Comparison Between Existing Online Trackers and the Proposed ReTracker. Retracking target points in a video sequence after long-term occlusions is challenging due to significant scene changes, where current state-of-the-art online trackers often struggle. In contrast, the proposed ReTracker pipeline achieves robust and accurate continuous tracking of target points upon reappearance, effectively handling large viewpoint and appearance variations.
