How does Re-Identification work?

In this episode, Florian Matusek explains how Re-Identification of objects in video surveillance works. This technique is increasingly being used for both object tracking as well as forensic search applications but there are some caveats to consider. Discover how Re-ID identifies objects under the hood and how it is being used in practice.

Thank you for the great video! I would love to learn how to build a ReID dataset!

Interesting subject, is there any supplier you can recommend on re-identification? Secondly privacy is a major subject, which measures are in place? In basis it means you can follow/track people.

Re-ID is not offered as a feature per se but embedded into an application, typically forensic search. For that I would look at the usual suspects like Idemia, Irisity, Briefcam, Oosto etc.
About privacy, as mentioned this is not biometric because it can only identify people at a specific moment in time. In that regard it is similar to tracking someone over a single camera. Privacy measures are available at the application layer, e.g. granular privileges and privacy masking by default on search results.
