multimodal images in medical imaging and is also effective for optical sections in
a z stack [93]. Mutual information content is a measure of the statistical
dependence, or information redundancy, between the image intensities of cor-
responding voxels in adjacent optical slices. Maximal values are obtained if the
images are geometrically aligned. The main advantage of this method is that
feature calculation is straightforward, since only gray-level values are used, and
the accuracy of the methods is thus not limited by segmentation errors.
