Intrinsic images aim at separating an image into reflectance and illumination layers to facilitate analysis or manipulation. Most successful methods rely on user indications [Bousseau et al. 2009], precise geometry, or need multiple images from the same viewpoint and varying lighting to solve this severely ill-posed problem. We propose a method to estimate intrinsic images from multiple views of an outdoor scene at a single time of day without the need for precise geometry and with only a simple manual calibration step.
