Abstract:
1. An image registration apparatus for registering a first image and a second image with respect to each other, the image registration apparatus comprising: an image providing unit for providing a first image of a first object and a second image of a second object, wherein the first object and the second object are of the same type, a model providing unit for providing a model of the first object and of the second object, wherein a number of model elements of the model and neighboring relations between the model elements are fixed, an adaptation unit for adapting the model to the first image for generating a first adapted model and to the second image for generating a second adapted model, wherein the adaptation unit is adapted to determine an internal energy by registering a shape model with the provided model and by determining deviations between the shape model and the provided model for adapting the provided model to the first image and to the second image, and a corresponding image elements determining unit for determining corresponding image elements in the first image and in the second image based on spatial positions of first image elements in the first image with respect to the first adapted model and spatial positions of second image elements in the second image with respect to the second adapted model.
