Transformation determination means and method for determining a transformation for image registration

摘要

The invention relates to a method for determining a transformation for image registration of a first image relative to a second image, the method comprising the steps of: determining a test series of test elements, wherein each test element comprises a test transformation and a test value, wherein each test element of the test series such The following is determined: determining the test transformation of the test element based on a predetermined sequence of test transformations and / or based on one or more previously determined test elements of the test series, transforming the first image with the determined test transformation, determining a difference image based on the transformed first And the second image, determining the test value of the test element based on the difference image such that the test value is a measure of an extension of a frequency distribution of values of pixels of the difference image in the direction in which the values of the pixels increase, is - determining a minimum test value based on the test values comprised by the test elements of the test series, - determining the transformation which is the test transformation of a test element comprising the minimum test value.
