New QPID method targets association instability for cheaper multi-object tracking annotation

Researchers have developed QPID (Query-Propagation Instability and Diversity), a novel active learning method designed to reduce the cost of annotating data for multi-object tracking (MOT) models. QPID focuses on identifying video clips where track states are unstable, meaning small perturbations can lead to significant changes in tracking predictions. By measuring localization drift and confidence discrepancies under these perturbations, QPID pinpoints clips that are crucial for improving association accuracy. The method also incorporates diversity in selection to avoid redundant annotations, demonstrating strong performance on datasets like DanceTrack and SportsMOT. AI

IMPACT QPID could significantly reduce the cost of creating training data for multi-object tracking systems, potentially accelerating their development and deployment.
