YOLO detection false negative

[Bibiw1]

Hello.
I launched yolo detection with video stream(IP-camera).
Picture:

There's two cars, but algorithm detected only one.
Can I tune program to fix it? Help me plz

if you want a perfect one, then you have to train one for yourself. read about threshold, and confidence. it can also help.
but at the end algorithm can't do everything, for practical scenario, you have to take care of image, size of object, exposure are and all that.

okay, thank you.
I am asking about, maybe, settings of algorithm, like sensetivity. i want to decrease false negative by false positives. hope you can undestand me

Try to change the values of some parameters in yolo3.cfg, for example
ignore_thresh, which is 0.7 by default.
