Tomographic reconstruction from projections with unknown view angles exploiting moment-based relationships

In this paper we describe a straightforward, yet effective method of recovering angles from a set of tomographic projections when the view-angles are completely unknown. Existing works on this problem have consistently assumed availability of projections from a large number of angles as well as made assumptions on the underlying distribution of angles to aid reconstruction. We make no such assumptions, and yet show a principled technique which is empirically validated, and quite robust to noise.
