V astTrack consists of a few attractive properties: (1) V ast Object Category . In particular, it covers targets from 2,115 categories, significantly surpassing object classes of existing popular benchmarks ( e.g ., GOT -10k with 563 classes and LaSOT with 70 categories). Through providing such vast object classes, we expect to learn more general object tracking.

Although this problem is significant for safer and smarter driving systems, the exploration of this problem remains limited.

The essence of simultaneously solving cross-domain tasks is to enhance the general-izability of the encoder.

Note, the direct FC link and SC detour form a cyclic loop inherited from both SC and FC topology.
