One keytask in modern medical imaging is image registration. It is the task of spatially aligning two or more images. A major problem is the similarity of images. To measure similarity, so-called distance measures are applied. We present a novel measure using Schatten-q-Quasinorms which are based on Singular Value Decompositions of a matrix of the images' gradients. The theoretical background is discussed and promising results are presented.
