I have been struggling to get accurate labeling of small body parts (Drosophila leg tips) despite using an extensive training dataset (800 frames from 5 diff animals males+females). I have tried lowering pos_dist_thresh to 9 and used 1 for glo_scale instead of .8 (also used imgaug). The resulting network was way too conservative (had hard time labeling even the obvious body parts that worked with the default settings). I did 800k iterations.
My video is 1300x900 and leg tips are usually 12-15 pixel in diameter. Any suggestions to improve labeling?
Thanks so much,
