Support for Selective Person Tracking in Multi-Person Videos

[DavidTu21]

Hi there!

Firstly, I'd like to extend my heartfelt gratitude for the incredible work on this project. The functionality and performance have been outstanding, and it's been instrumental in my current work involving pose estimation.

In my current setup, I'm dealing with videos that feature multiple people. VitPose efficiently identifies all individuals, but for my purposes, I need to track a specific person through the video. This is crucial because, as noted in MotionBert documentation, they currently support single-person analysis only. In MotionBert, it's mentioned: "Note: Currently we only support single person. If your video contains multiple person, you may need to use the Pose Tracking Module for AlphaPose and set --focus to specify the target person id."

Given this requirement, I'm curious if we have a similar functionality in VitPose or if there's a workaround that can be implemented. Specifically, I'm looking for a feature that would allow me to select and track a single person in a video with multiple individuals, akin to the '--focus' option in AlphaPose.

Thank you once again for your amazing work and support.
