Finding canonical views by measuring features on the viewing plane

Canonical views are referred to the classical three-quarter views of a 3D object, always preferred by human beings, because they are stable and able to produce more meaningful and understandable images for the viewer. Unlike existing methods to measure features in the 3D space for view selection, this paper proposes to measure features on the viewing plane, taking into account the influence of feature deformation due to perspective projection on view evaluation. Meanwhile, we try to have more features perceptible instead of having preferred features displayed more in a good view, which is aimed by existing methods. As a result, we can effectively obtain canonical views with only geometry computation, without troublesome semantic computation, which are always needed in existing techniques for obtaining good views.
