I have converted ours.png to (lossless jpeg) and the
dicomized that file. Using a DICOM viewer I played with the
exposure (called Window/Level) while comparing to vendor.jpg.
It seems as if the vendor applies non-linear corrections
independantly to two or three areas: inside teeth, inside
bone, outside either tooth or bone.
I so feels lbecause I can sort of approximate each of those
areas but not all three of them at once.
So, perhaps some segmentation is going on before
