Researchers have developed HieDG, a novel framework for multi-animal tracking that addresses challenges like uniform appearance and high density. Unlike previous methods that rely on heuristic associations or continuous geometric embeddings, HieDG discretizes geometric cues such as position, scale, and velocity into stable tokens. These discrete tokens are integrated with visual embeddings within a query-based tracker to improve identity consistency. Experiments on animal-specific and generic multi-object tracking benchmarks show that HieDG achieves state-of-the-art association performance. AI
