Abstract — This paper focuses on finding techniques that can be used in cardiac magnetic resonance images semiautomatic registration in a simple and fast way. The suggested technique depends on using parts of one image selected by the user to be matched with another image of the same patient in order to find control points or correspondences between those two images. The experiment focuses on three techniques and compared between them, all techniques used the Gaussian pyramid in order to sample the images to the third pyramid level; which reduces the image size and so increases the performance time of matching; and then segment the target image into smaller images to be compared with the template image. The third matching technique is then used in intrasubject cardiac MRI rigid axial registration.
