Title:   Image-consistent Meshes


Given two or more images of an object, we aim to generate new, realistic
images of the object from different positions and orientations.  The two
common approaches to this are image interpolation and 3D shape estimation.
We propose a morphing-based approach that spans aspects of both of these
approaches.

Starting from a sparse set of feature correspondances between images, we
create a triangulated mesh over this feature set.  We adjust this mesh
using an image consistency measure, to obtain a local affine surface
approximation.  Image interpolation is then performed using this mesh to
obtain new synthetic images.  The method does not require explicit 3D shape
calculation, and yet it captures much of the 3D projection effects.
