opencv multi channel element access

Question

I\'m trying to learn how to use openCV\'s new c++ interface.

How do I access elements of a multi channel matrix. for example:

Mat myMat(size(3, 3), C         


        

Answer 1

Vic you must use Vec3b instead of Vec3i:

for (int i=0; i(i,j)[0] = 0;
            image.at(i,j)[1] = 0;
            image.at(i,j)[2] = 0;
        }
    }
}
