Bayesian Registration for Anatomical Landmark Detection [PDF]

3rd IEEE International Symposium on Biomedical Imaging: Macro to Nano, 2006., 2006
In order to perform medical image registration, landmarks are used to settle correspondences between images. A landmark is a voxel in the image that corresponds to a well-defined point in the anatomy. Manual landmarking is a difficult, tedious and time-consuming procedure that would gain to be automated.
