Tracking vs Identification #12

Hi,

Thanks for providing this wonderful repository!

My doubt is that in real-world setting, where you have multiple persons entering the camera feed and you need to ID them for a longer duration, then in that case tracking is better option or reidentification?

In general also, how would one differentiate between object tracking vs object reidentification?

Thanks,

@Ashutosh1995 Re-identification is a complement application in surveillance systems. It is the process of identifying persons across different camera views using a query, while tracking typically happens in a single camera view. For example, lets say you have 5 cameras and these feeds are non overlapping. Tracking in such an environment across these non overlapping caameras is impossible or at best, very challenging. This is where re-identification comes in; the ability to find the same person over and over again when they transition into different camera views. In the same camera view, tracking is more logical. But, if tracking stops for some reason, it is important to find that same person again and continue tracking. These are the main differences. Each has a different or complementing role.
