As a fundamental task in computer vision, multi -object tracking (MOT) has gained increasing attention due to its commercial and academic potential. However, accurately tracking multiple objects is highly challenging. The problems of object occlusion, deformation, and real-time requirements have long been obstacles to be tackled in the field of multi -object tracking. In this paper, we first propose a novel approach to address the problem of tracklet fragmentation caused by occlusion and deformation by establishing a global linking model to obtain global information on trajectories. Then, we r...
