Perhaps that top left corner artifact of Floyd-Steinberg dithering could be reduced by copying the left edge and top edge outwards. Like to make the picture 10-20 pixels wider and taller by adding 10-20 copies of the left edge and the top edge.
It feels to me that the Tucson images with gamma correction applied are overall a little bit darker then the real image. I feel like the non gamma corrected version is more matching. Could you analyze that? Maybe it's just me / an optical illusion.
Well, there's a lot of subjectivity to it, and using a geometric function (square root) is an over-simplification. If we wanted to REALLY get it right, we'd have to look up the DICOM-14 spec or something like that and get an accurate perception curve.
