What's a wind? When you say diff.by row, do you mean the mean of one whole target row minus the mean of the whole corresponding row in the template, or do you mean on a pixel by pixel basis instead of by row or column?

Make sur eyou convert to double before taking the difference. Also, you might want to take the absolute value of the differences.
