As same with Matlab, we can use inequality ">,<,==,>=,<=".
Firstly, we check equal to '0' or '>0', the result is output to '255' if satisfied.
Divide by 255 then elements have left '0' or '1'
And sum all of the element, then we can get the number of zero.
Source code is here..
Mat a = Mat(5, 5, CV_8UC1);
randn(a, 0, 1);
Mat b = (a == 0) / 255;
Mat c = (a > 0) / 255;
cout << "Input matrix matrix a = " << endl;
cout << a << endl;
cout << "number of 0 = " << sum(b);
cout << ", number of over 0 = " << sum(c) << endl << endl;
cout << "matrix b = " << endl;
cout << b << endl;
cout << "matrix c = " << endl;
cout << c << endl;
