Better workflow for unequal brightness across image
PeTrack can struggle if the brightness between image regions differs too much. It may be helpful to use some image processing to reduce the brightness range of the image.
There already exist some options in PeTrack for playing with brightness and constrast, but new methods based on e.g. gamma correction, histogramm equalization, etc. could be explored as well. The data from the fete de lumiere might be a nice testbed for evaluating increases in accuracy.
