QUICK METHOD

The quickest way is to export images is to login to the ReID server and change the link to "/algorithm". 

Navigate to the "Export by Event". This is where you can select any 1 hour range to do your analysis.

NOTE: The zip file size may be huge depending on your traffic. It could also contain millions of images

How to Check for Accuracy?

Once you extract all the image folders from the zip file, you will see the top-level folder being the ReID (Unique Person) and the 2nd-level folder is the sensor or location which this person has been seen

What you can do is to check some images in each folder to make sure that they are the same person.

From 1 folder

From 2nd folder

You may check randomly around 100-500 ReID folders and compute the result if there is any mismatch between the sub-folders, meaning we confuse 1 person with another person.
