1. A method comprising:
generating a plurality of two-dimensional (2D) images from a first three-dimensional (3D) model of a subject's dentition;
adjusting one or more image attributes of the plurality of 2D image to produce one or more modified 2D images;
projecting each of the modified 2D images onto the first 3D model to form a segmented 3D model, wherein conflicts between segmentation boundaries when projecting the modified 2D images onto the first 3D model are resolved statistically on a per-location basis; and
outputting the segmented 3D model.
