QTrack: Query-Driven Reasoning for Multi-modal MOT

QTrack is an end-to-end vision-language model designed for query-driven multi-object tracking (MOT). Unlike traditional MOT which tracks all objects in a scene, QTrack selectively localizes and tracks specific targets based on natural language instructions while maintaining temporal coherence and identity consistency.

Description

Multi-object tracking has traditionally focused on estimating trajectories of all objects. QTrack introduces a query-driven tracking paradigm that formulates tracking as a spatiotemporal reasoning problem conditioned on natural language queries.

Key Contributions

RMOT26 Benchmark: A large-scale benchmark with grounded queries and sequence-level splits to enable robust evaluation of generalization.
QTrack Model: An end-to-end vision-language model that integrates multimodal reasoning with tracking-oriented localization.
Temporal Perception-Aware Policy Optimization (TPA-PO): A structured reward strategy to encourage motion-aware reasoning.

Benchmark Results

QTrack achieves state-of-the-art performance on the RMOT26 benchmark.
