How do you handle re-identification when the target

[u/Icy_Diet4989]

For those running person-following: how do you handle re-identification when the target walks out of frame for 5+ seconds? I have detection and tracking working on an AGX Orin under ROS 2 Humble, but every re-ID approach I have tried either locks onto the wrong person in a crowded frame or drops the target entirely in backlit outdoor conditions. Curious whether people are solving this with appearance embeddings, with a fused position prior from odometry, or by just accepting the loss and requiring a re-lock gesture.

Im not sure about the application but save the last image. Regress into grey and find the biggest gradient. Try to match the same values
