# Revision history [back]

Hi, I need to use calcBackProject and then display the exact number.

    for ( int i = 0; i < backProj.rows; i++ )
{
for ( int j = 0; j < backProj.cols; j++ )
{
cout << int(backProj.at< uchar >( i, j )) << " ";
}
cout << endl;
}


But its max value is 255 because of "uchar". I tried to use

    Mat backProj( slid_.rows, slid_.cols, CV_64FC1 );


and then display it

    cout << backProj.at< double >( i, j );


but it does not work.

I really need the exact numbers which are bigger than 255. I don't want to scale it down or use normalize before. Can I make it by calcBackProject? Thank you.
