Question about the usage of q_q_dist

[justopit]

Hello! your reranking is a good job! However, there is a problem about your usage of q_q_dist. Without q_q_dist, it seems that your reranking would drop a lot. I do the experiments below

mAP of No reranking	mAP of reranking with q_q_dist	mAP of reranking without q_q_dist
70.3	85.7	71.9
23.9	34.7	25.5
24.0	35.2	25.5

It is so weird. Could you explain it?

Hello, @zhunzhong07. I encountered a similar problem. I also wonder why to use q_q_dist? I mean, in practical ReID scenarios, there may be not enough query images for q_q_dist.

If the algo requires q_q_dist, then it is not practical?
In real-world application query is a track of images (multi-shot) and each person in the gallery also contains a large number of images. Is your algo is applicable?
