Grouper Moon video - what tracker (detector and tracker) to start?

Howdy – I’ve uploaded a video (a few actually) to the VIAME web portal (username bsemmens), and I’m looking for some guidance for which tracker to start with. We would like to pull out as many fish as possible from high resolution video for instance pattern recognition work (facial recognition for natural tag mark recapture). Both the boxing and tracking are a very important part of this – tracking is important so we don’t produce hundreds of images/boxes of the same fish and ultimately swamp the instance pattern recognition workflow. Advice appreciated!!
