Efficient 3D dental identification via signed feature histogram and learning keypoint detection

作者:

Highlights:

• We use a machine learning method to accurately detect keypoints on dental models.

• A novel local shape descriptor is proposed which can be efficiently computed.

• A highly efficient and robust dental identification algorithm is proposed.

• The proposed method is about 80 times faster than traditional 2D based methods.

• Promising results are achieved for single tooth identification.
