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 post-processing ?
