Critical Motions in Euclidean Structure from Motion
We investigate the motions that lead to ambiguous Euclidean scene reconstructions under several common calibration constraints, giving a complete description of such critical moti...

Determining the Radiometric Response Function from a Single Grayscale Image
A method is presented for computing the radiometric response function of a camera from a single grayscale image. While most previous techniques require a set of registered images ...

Voxel Carving for Specular Surfaces
We present an novel algorithm that reconstructs voxels of a general 3D specular surface from multiple images of a calibrated camera. A calibrated scene (i.e. points whose 3D coord...

Homography normalization for robust gaze estimation in uncalibrated setups
Homography-based glint-normalization is presented as a novel gaze estimation method for uncalibrated setups. The method is geometrically and empirically demonstrated to be robust ...
