Hi everybody ! I'm going to start by showing you the debugger output :

Here's my code :

    float sum(cv::Mat img, int startedY, int startedX, int w) {

here's a portion of /usr/local/include/opencv2/core/mat.hpp :

inline Mat::Mat(const Mat& m)

    refcount(m.refcount), datastart(m.datastart), dataend(m.dataend),

    if( m.dims <= 2 )

        step[0] = m.step[0]; step[1] = m.step[1];
    }
    else
    {
        dims = 0;
        copySize(m);
    }
}

Any ideas how I could fix this issue?
