Right way to normalize mammogram dataset?

  1. What is the right way to normalize a mammogram dataset?

  2. Let’s say I get the center slice from a tomogram dataset and create a new dataset of these slices, now what would be the right normalization technique?

It depends. You should be able to get OK results with whitening (setting mean -> 0 and variance -> 1). There are also several histogram normalization methods that can be used. However, it’s worth trying the easiest way first and then evaluating if changing it makes a difference to results.
