Hi all, I am testing in my application opencv's backgroundSubtractors mog, mog2 and gmg. All 3 reduce the FPS of my application ALOT. With mog and mog2 I get around 17 fps and with gmg I fall down to 5!
I have re-examined my code and I know I pass around the images as references. There is 1 deep copy involved when grabbing the image from camera, but other than that I work with pointers.
Are the algorithms THAT power hungry? Note that I run only one subtraction method at a time on CPU (not gpu). The processor is a core i7 though and it seems reasonable to assumd in should be able to cope. Or am I wrong ?
