Counting errors (miss)

[user511235]

Hello Andrey,

Thank a lot for this code it will be very useful for me. I have some questions. Why counting mistakes happen when I use this code on other video?

1* When I set exit green mask at 1280px - 150px, this algorithm count 19 cars (real is 25 cars).
2* When I set exit green mask shorter/longer at 100px or 250px algorithm count 0 cars.

How to properly set up exit mast for counting?

I have example with video for 1* situation.
