Missing MOSSE and medianflow trackers

It seems that a number of trackers, including MOSSE and medianflow, have been removed from OpenCV 4.5.1. Could you consider adding them back in?

They may not be as accurate as some of the other trackers, but they are SIGNIFICANTLY faster, and hence still serve a purpose for some use cases.

You can find all info related to tracking API changes here:

They are not removed completely - just moved in “legacy”.

Thanks! Let’s hope they don’t disappear from there in the near future then!

if MOSSE disappears, ping me. the API needs an overhaul. I want subpixel/float coordinates and I want detection and update to be separate steps so I can “steer” the tracker state.
