Adults Tracking
Pre-process the input video to make it suitable for Trackmate analysis. These steps include image inversion, as Trackmate algorithm recognizes white spots in a dark background. It uses Top-Hat processing to subtract the background and adjusts brightness and contrast.
A TrackMate tutorial can be found here.
FPS reduction
We found 10 fps to be suitable to track adult fish movement. It's possible to change the framerate using this plugin's FFmpeg tool

The user can choose between AVI, TIFF or MP4.
