Claim 9:
10. The apparatus of claim 1, wherein the one or more memories are further configured to store information indicating a reference slope and a reference size for teeth shapes of the plurality of pre-processed images, and information indicating a reference pixel value for identifying a preset feature, and
wherein the one or more processors are further configured to:
rotate each of the plurality of first teeth images so that a teeth shape of each of the plurality of first teeth images has the reference slope;
enlarge or reduce each of the plurality of rotated images so that a teeth shape of each of the plurality of rotated images has the reference size;
remove a region other than a region representing teeth from each of the plurality of enlarged or reduced images, the region representing the teeth being a region having a preset width and height based on a center point of a lower end of each of the plurality of enlarged or reduced images; and
generate the plurality of pre-processed images by removing a region matching the reference filter including one or more pixels having the reference pixel value from each of the plurality of images from which the region other than the region representing the teeth is removed.
