Table 4. Pseudocode of proposed method.

Algorithm: proposed method
Step A	Input the ground-truth imaging data together with their labels.
Step B	Co-registration to Talairach Coordinate by Rigid Registration.
Step C	Pick up the key-slices by ICV (more than half of maximum), with 10× undersampling factor.
Step D	Produce displacement field for each key slice for each subject.
Step E	Submit the displacement field to the classifiers.
Step F	Report the classification performance based on a 50×10-fold cross validation.
Step G	Report the AD-related regions with the points whose displacement magnitude is larger than five.
