Abstract
Image registration very often used to be a tedious task which had Si to be performed manually. According to an exemplary embodiment of the present invention, a non-rigid image registration by an iterative refinement process based on a combination of landmarks with similarity values is proposed. Advantageously, a very fast and robust method maybe provided.
Claims9
Method of registering a first image and a second image, the method comprising the steps of:
- selecting at least one first landmark in the first image;
- selecting at least one second landmark in the second image;
- and registering the first and second images by using a similarity value which relates to a similarity of a first region in the first image determined by the at least one first landmark and a second region in the second image determined by the at least one second landmark;
- wherein the at least one first landmark corresponds to the at least one second landmark.
Image processing device, comprising:
- a memory for storing a first image and a second image;
- and an image processor for registering the first image and the second image, wherein the image processor is adapted to perform the following operation:
- selecting at least one first landmark in the first image;
- selecting at least one second landmark in the second image;
- and registering the first and second images by using a similarity value which relates to a similarity of a first region in the first image determined by the at least one first landmark and a second region in the second image determined by the at least one second landmark;
- wherein the at least one first landmark corresponds to the at least one second landmark.
Computer program for registering a first image and a second image, wherein the computer program causes a processor to perform the following operation when the computer program is executed on the processor:
- selecting at least one first landmark in the first image;
- selecting at least one second landmark in the second image;
- and registering the first and second images by using a similarity value which relates to a similarity of a first region in the first image determined by the at least one first landmark and a second region in the second image determined by the at least one second landmark;
- wherein the at least one first landmark corresponds to the at least one second landmark.
