Program for counting black and white pixel values in pictures

Count the number of white pixels in the binary image

// Count the number of white pixels in the binary image 
// Input binary image , Returns the number of white pixels 
int bSums(Mat src)
{

    int counter = 0;
    // Iterator access pixels   
    Mat_<uchar>::iterator it = src.begin<uchar>();
    Mat_<uchar>::iterator itend = src.end<uchar>();
    for (; it != itend; ++it)
    {
        if ((*it)>0) counter += 1;// After binarization , The pixels are 0 perhaps 255  
    }
    return counter;
}
