The query folder of Market-1501 for what? about market-1501_attribute

[layumi]

Hi @ciwei123,
Just for a quick explanation,

• gt_query is for multiple-query evaluation.
• gt_bbox is for detection quality evaluation.

More details can be found at http://www.liangzheng.com.cn/Project/project_reid.html.

4) "gt_query". This folder contains the ground truth annotations. For each query, the relevant images are marked as "good" or "junk". "junk" has zero impact on search accuracy. "junk" images also include those in the same camera with the query.
5) "gt_bbox". We also provide the hand-drawn bounding boxes. They are used to judge whether a DPM bounding box is good.

@layumi Thanks your reply! That means that 'gt_query' and 'query' are for evaluate the model, right?
And another question, I have trained a reid model 'model.ckpt-300000', how I evaluate the model? Thank you again!!

[layumi]

Which framework did you use?
I do not know with the ckpt file.

If you use python, especially pytorch, you may refer to https://github.com/layumi/Person_reID_baseline_pytorch/blob/master/evaluate.py
If you use matlab, you may refer to

@layumi Thank you very much! And I have learned your "tutorial", that is very useful .Thank you again.Now, I have an another question.I have trained the model from "https://github.com/nwojke/cosine_metric_learning" , and this link code have created "query.mat" and "test.mat", but when I evaluate the model ,I need a ”query_max.mat“ file.How I can get the file according the "query.mat"? Looking for your reply.

[layumi]

Why you need a 'query_max.mat'?
You want to conduct a multiple-query evaluation?

[ciwei123]

@layumi Yes! I want to conduct a multiple-query evaluation. Because I see the following paragraph：" While the single-gallery-shot CMC is well defined, it does not have a common agreement when it comes to the multi-gallery-shot setting, where each gallery identity could have multiple instances. " Could you help me get the "query_max.mat" file according the "query.mat" ? Looking for your reply.Thank you very much.

@ciwei123
Please check the original code of Market-1501. It includes a code for multiple-query evaluation http://www.liangzheng.org/Project/project_reid.html , which generates query_max and query_avg.

@layumi Thank you .You really give me a lot of help. I want to combine a REID code for my tracking, I find a REID code Rank 1=79.1, mAP=56.68 in Market-1501. I want to find a better performance code. Could you give me some advice about REID open source ？Thank you very much!

@layumi I will study it .I don't know how to express my gratitude. If I can help you something, please contact me.Thank you again.
