Can We Calibrate a Camera Using an Image of a Flat, Textureless Lambertian Surface?
Abstract. In this paper, we show that it is possible to calibrate a camera using just a flat, textureless Lambertian surface and constant illumination. This is done using the effec...

Interactive Models From Images of a Static Scene
FXPAL's Pantheia system enables users to create virtual models by `marking up' a physical space with pre-printed visual markers. The meanings associated with the markers...

Direct Illumination with Lazy Visibility Evaluation
In this paper we present a technique for computing the direct lighting in a three-dimensional scene containing area light sources. Our method correctly handles partial visibility ...

Sparse Representation of Cast Shadows via L1-Regularized Least Squares
Scenes with cast shadows can produce complex sets of images. These images cannot be well approximated by lowdimensional linear subspaces. However, in this paper we show that the...
