 * Bundle adjustment, i.e. an overall optimization to refine the 3D points and the projection matrices by minimizing the reprojection error of the 3D points back to each view. 
 * Self-calibration to estimate the camera intrisic parameters for each view, and transform the 3D structure from the projective to metric space.
