Robust Anatomical Landmark Detection with Application to MR Brain Image Registration

Accurate matching of anatomical structures is a key step in many medical image processing and analysis tasks, e.g., deformable image registration [1–5], organ motion correction [6], and imaging biomarker identification [7–10]. For example, the goal of deformable image registration is to maximize the image similarity by spatially warping one image to another. To achieve this, accurate determination of matching structures between images is crucial. Correspondence detection can be achieved by using either image intensities or image features (e.g., SIFT [11], geometric invariant moments [12], and wavelet transformation [13]).
