Abstract
Comparing first and second images taken on different imaging systems and under different exposure conditions is achieved by the steps of: applying a model to the data representing the first image, which model simulates at least one process step in the creation of said first image, to derive a representation of the first image at a level of processing common to the creation of the second image; and applying a further model to said representation, which model simulates at least one process step in the creation of said second image, to derive a further representation of the first image which corresponds to the same level of processing as said second image.
