Question about the usage of q_q_dist #28

Open justopit opened 4 years ago

justopit commented 4 years ago
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.

@zhunzhong07 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?
