3. The method of claim 2 , wherein selecting the subset of the points in the subject image is based on at least one ambiguity criterion with respect to the first data.
4. The method of claim 3 , wherein each atlas image comprises a plurality of points, and each atlas image point is associated with a label indicative of whether the associated atlas image point is classified as the at least one structure; wherein registering the subject image with the plurality of the atlas images associates the registered subject image points with the labels that are associated with the atlas image points that were mapped to the registered subject image points; wherein generating the first data comprises classifying a plurality of the subject image points as to whether those subject image points belong to the at least one structure based on the labels associated with those subject image points; and wherein selecting the subset of the points in the subject image comprises selecting the subset of the points as the subject image points that are associated with estimated structure classification accuracy data below a threshold.
