“…In 3D reconstruction from multi-view images, there are several processes, including image registration, which is the transforming process of different sets of data into one coordinate system. There are existing works on 2D medical image registration [ 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 ]. Since point cloud coordinates are used in our 3D teeth reconstruction, the 3D registration is more proper.…”
