Question

I create a:

CvRect aaaaa=CvRect(0,0,10,10);

but I got this error:

error C2661: ‘CvRect::CvRect’ : no overloaded function takes 4 arguments

I don’t undestand why i got this since it takes 4 arguments.
I’m using c++ and Opencv 2.1

Answer 1

From reading the reference guide for CvRect it seems that it is a struct with no constructor. But there is a helper method named cvRect() that can be used to create a CvRect:

CvRect aaaaa = cvRect(0, 0, 10, 10);
