you can use multiply:
Mat a(1,1,CV_8UC3,Scalar(20,40,60));
cerr << a << endl;
multiply(a, Scalar(1.2,0.5,.2), a);
cerr << a << endl;
[ 20, 40, 60]
[ 24, 20, 12]
(i can only guess, but since the *
operator applied on Mat is a matrix multiplication, which does not make sense for a Scalar, there is no overload for *=
)
