Opencv multiply scalar and matrix

Question

I have been trying to achieve something which should pretty trivial and is trivial in Matlab.

I want to simply achieve something such as:

cv::Ma         


        

Answer 1

For java there is no operator overloading, but the Mat object provides the functionality with a convertTo method.

Mat dst= new Mat(src.rows(),src.cols(),src.type());
src.convertTo(dst,-1,scale,offset);

Doc on this method is here
