There are four limitations: 1. In this experiment, single dataset training and single dataset testing cannot verify the generalizable ability of models, it should conduct experiments on large-scale datasets. 2. The efficiency of such pairwise matching is very low, making it difficult to be used in practical application systems. 3. I hope to see that you can compare your model with ResNet-IBN / ResNet of FastReID, which is practical work in the person Reid task. 4. I think the authors only use the transformer to achieve the local matching, therefore, the contribution is limited.
