DanielXiang/3Dbullets: 3D Bullet Rotations

A package which contains methods for the leveling and rotation of 3D images of bullet cartridges. The leveling process involves taking a linear regression over the i and j coordinates and producing a best fit plane, and then we adjust the depth values so that the best fit plane is a level plane. The rotation process involves multiplying coordinates by a rotation matrix, and then bilinearly interpolating the neighboring 4 points of the resulting non integer coordinates.
