Abstract
A computer implemented method is disclosed. The method includes obtaining a first and second images for comparison, globally registering the first and second images, calculating for pairs of a first patch of the first image and second patch of the second image a similarity measure which is a product of luminance and contrast components and a normalized structure component, each component taking a value between 0 and 1 and determining similarity of the images based on the calculated similarity measure. Relating computer program product and data processing system are also disclosed.
