I have tried histogram equalization from several software packages but the
images contain severe vertical banding. I don't know if this is caused by
how the intensities are mapped to the monitor or graphics card or both.
This makes if hard to find vertical flaws. Different monitors/graphic
cards seem to give different results. Does someone have a suggestion on
how to fix this or montitor/graphics card recommendations if that is the
problem. These are 4096 gray scale images.

The images are taken using 4 Mev with a tungstun collimator at the source
only. Also we are using a linear intensity response CCD 1536 X 1024
detector.

Thanks for your help this has suggested options that may help with the
problem.
