Abstract
Multi-object tracking in crowded scenes remains challenging due to occlusions, appearance ambiguity, and unreliable detections. We propose a tracking framework that leverages both body and face cues to improve identity consistency. Our method uses YOLOv8s to detect persons and faces, followed by a spatial association step to link them into person-level observations. We then employ DINOv2 to extract feature embeddings from detected regions, which are used within a tracking pipeline that combines motion and appearance information. The tracker adopts a cascade matching strategy to associate detections across frames and handle challenging cases such as occlusions and missed detections. Experimental results on a sequence of MOT17 dataset demonstrate that incorporating complementary cues can help maintain identity consistency, while also revealing limitations in dense scenarios.
