SYSU-30k

SYSU-30k contains 30k categories of persons, which is about 20 times large rthan CUHK03 (1.3k categories)and Market1501 (1.5k categories), and 30 times larger than ImageNet (1k categories). SYSU-30k contains 29,606,918 images. Moreover, SYSU-30k provides not only a large platform for the weakly supervised ReID problem but also a more challenging test set that is consistent with the realistic setting for standard evaluation. Figure 1 shows some samples from the SYSU-30k dataset.
