Download the raw datasets DukeMTMC-VideoReID, MARS and then unzip them under the directory like

Auxiliary information exploiting modules TOC, STS and SCP can only be used for DukeMTMC-VideoReID. The pickle files related to the three modules are placed in AuxUSLReID/pickles and are generated from DukeMTMC-VideoReID.
The parameters related to the methods we proposed are introducted as follows. Modify the config (config/*.yml) as our paper suggests before training.
