Unformatted text preview: aper we investigated the feasibility of generating new views of a scene from two basis views. Under an assumption of monotonicity, it was shown that
the problem is theoretically well-posed. This result is
signi cant in light of the fact that it is not possible to
fully recover the structure of the scene due to the aperture problem. Furthermore, we demonstrated that a
particular range of views can be generated by linear
interpolation of the basis images, if the basis images
are rst recti ed. This result provides a theoretical basis for morphing techniques based on geometric image
interpolation 1, 7, 8, 9, 10 and provides a simple way
of generating new views of a scene. Finally, a scanline algorithm for interpolating two basis images was
described that requires only a small number of userprovided feature correspondences. The application of
the method was demonstrated on real images. 13

locally violating the assumption of monotonicity and causing local blurring in the interpolated image. Other local
artifacts, such as an incorrect region near the top of the cube in I1:5 , result from errors in correspondence. 8...
