When I got a 100x100 image, I wanted to scale it to 400x400 by bicubic. Is opencv use biucbic to upsample twice(i.e. first time:100x100->200x200, second time:200x200->400x400) or opencv use other formula to upsample it?

As the flowing :
resize(srcImg,upsample,Size(),4,4,INTER_CUBIC);
is it doing the flowing steps?
first step : resize(srcImg,upsample_first,Size(),2,2,INTER_CUBIC);
second step : resize(upsample_first,upsample_second,Size(),2,2,INTER_CUBIC);
