Im using openCV C++ Im need to convert a single channel image to 3 channels image. So i can use this: <code>cvCvtColor(result,gray,CV_BGR2GRAY);</code> I cannot do that because the result img is a single channel image. Any ideas?

You should use <code>CV_GRAY2BGR</code> instead of <code>CV_BGR2GRAY</code>.
