I want to close shadow detection on BackgroundSubtractorMOG2()(opencv.js ) I do some research on google and i find this C++ code:documentation

But I can't implement this code on my javascript code.basically following code doesn't work and get error

let fgbg = new cv.BackgroundSubtractorMOG2(500, 16, true,0);

BindingError: Tried to invoke ctor of BackgroundSubtractorMOG2 with invalid number of parameters (4) - expected (0,1,2,3) parameters instead

please have a look at the docs

there is no 4th argument, use it like:

let fgbg = new cv.BackgroundSubtractorMOG2(500, 16, true);

it's the last argument, true == detect shadows, false == don't.
