Exploiting Image Collections for Recovering Photometric Properties
Abstract. We address the problem of jointly estimating the scene illumination, the radiometric camera calibration and the reflectance properties of an object using a set of images...

Estimation of Multiple Directional Light Sources for Synthesis of Mixed Reality Images
We present a new method for the detection and estimation of multiple directional illuminants, using a single image of any object with known geometry and Lambertian reflectance. W...
