Final gasp (on this over-long posting): there was a curious and unexpected feature of those 3D images where 4 different images were tested together. Switching between Invert On versus Off in Image J did not produce so marked a transformation as expected (one expects the image to be turned inside out, like punching a hat to make a new one with the lining on the outside).
Read on. It’s not that I don’t understand Colin. I do. It’s ImageJ that I am struggling with. Having said that, however, I still think this package is much more powerful than the VP-8 Image Analyzer. Once we figure it out more completely, we may be able learn a great deal more about the image on the shroud.
