Light Waving: Estimating Light Positions From Photographs Alone
We present an algorithm to automatically estimate three-dimensional light positions from an unordered set of images. We collect images using a single stationary camera while manua...

Range Image Registration Based on Circular Features
Range sensing technology allows the photo-realistic modeling of large-scale scenes, such as urban structures. A major bottleneck in the process of 3D scene acquisition is the auto...

Determining the Skeletons of the Auroras
The auroral emissions observed in the high-latitude regions encircling the magnetic poles are a key element in studying plasmaphysical processes in the near-Earth space, the magne...
