Garden motion false positives due to trees and lighting

asked 2019-10-27 11:05:03 -0500


New to openCV here. I am trying to build a system to capture motion-activated photos/videos of the animal in my garden. Most of the motion detection algorithms I found online subtract the current frame from the initial frame, but that doesn't work outdoors as the lighting changes over the course of the day.

I currently subtract the current frame from the previous frame, however this still gives me a lot of false positives due to the wind moving the leaves in the trees.

Are there other algorithms I should look into in order to detect exclusively the sustained motion of foreground objects?

Where do you put camera? Above roof?

For now it's indoors at ground level, pointing through the window
