dc.description.abstract This dissertation proposes a new technique for generating an arbitrary virtual view of an object of interest given a set of images taken from around that object. The method enables the illusion of a camera viewing the object along an arbitrary path. The algorithm extends Xiao and Shah’s tri-view morphing scheme to work with wide baseline imagery. Our method performs feature detection and feature matching across three views then blends the real views into a virtual view. Tri-view morphing by itself is realistic when occlusion across the three views is minimal, but when it is applied to cases of more complex objects and wide baselines, occlusions lead to significant artifacts. We propose a new adaptive algorithm to solve these problems by 1) segmenting the views into object and background, 2) obtaining finegrained correspondences across the three views, and 3) constructing, when a border point in one view is occluded in one or two of the other views, a virtual correspondence for that point. Novel views are synthesized using barycentric interpolation, but occluded polygons are automatically eliminated from the interpolation procedure. In an empirical evaluation, we find that our modified tri-view morphing procedure is a dramatic improvement over the original procedure in cases of complex objects imaged with wide baselines. The result is a system allowing smooth and realistic animation of the virtual object over arbitrary viewing paths. en_US
