I'm never used C++ before, and I used OpenCV background subtraction MOG (Mixture of Gaussian) function in Python and I need to understand how the program works, the OpenCV program line 123 there's command
bgmodel.create( 1, frameSize.height*frameSize.width*nmixtures*(2 + 2*nchannels), CV_32F );.. I found the
.create function is to allocate new data from here with I assumed the parameter inside was
(int ndims, const int* sizes, int type), my question is what the * mean, is it multiplication or pointer?
