Abstract: Double Your Views: Exploiting Symmetry in Transmission Imaging

Zusammenfassung

For a plane symmetric object we can find two views - mirrored at the plane of symmetry - that will yield the exact same image of that object. In consequence, having one image of a plane symmetric object and a calibrated camera, we can automatically have a second, virtual image of that object if the 3D location of the symmetry plane is known. In this work, we show for the first time that the above concept naturally extends to transmission imaging and present an algorithm to estimate the 3D symmetry plane from a set of projection domain images based on Grangeat’s theorem.
