Eye reflection analysis and application to display-camera calibration
We present a novel technique for calibrating display-camera systems from reflections in the user's eyes. Display-camera systems enable a range of vision applications that nee...

Shape-from-Silhouette with Two Mirrors and an Uncalibrated Camera
Two planar mirrors are positioned to show five views of an object, and snapshots are captured from different viewpoints. We present closed form solutions for calculating the focal ...

Single View Modeling of Free-Form Scenes
This paper presents a novel approach for reconstructing free-form, texture-mapped, 3D scene models from a single painting or photograph. Given a sparse set of user-specified const...

Accuracy of Spherical Harmonic Approximations for Images of Lambertian Objects under Far and Near Lighting
Various problems in Computer Vision become difficult due to a strong influence of lighting on the images of an object. Recent work showed analytically that the set of all images of...

Closed surface reconstruction in X-ray tomography
We study the 3D reconstruction of a binary scene from X-ray tomographic data. In the special case of a compact and uniform object lying in a uniform background, the scene is entir...
