#4 Trouble with detection step

[Johanna Ott]

Hello,
while trying to track an individual bumble bee in a petri dish, I struggle with the detection step. I calculated the background as average of 100 pixels (I tried different numbers here before), and while it looks like it recognizes the bumble bee in the background page, it doesn´t show up in the detection - no matter what thresholds I try. The original video is recorded in red light, but pilot videos in white light showed the same result. How can I fix this?
Thank you,
Johanna Ott
