Abstract: We propose a multimodal free-form registration algorithm that matches voxel class labels rather than image intensities. Individual voxels axe displaced such as to minimize the Kullback-Leibler distance between the actual and ideal joint probability distribution of voxel class labels, which axe assigned to each image individually by a previous segmentation process. We evaluate the performance of the method for intersubject brain registration with simulated deformations, using a viscous fluid model for regularization. The root mean square difference between recovered and ground truth deformations is smaller than I voxel.
