The document describes a method for intrinsic image decomposition of outdoor scenes from multiple views. Intrinsic images aim to separate an image into reflectance and illumination components to facilitate analysis or manipulation. Previous successful methods rely on user input or precise geometry. The proposed method estimates intrinsic images from multiple views of an outdoor scene without precise geometry, using a few manual calibration steps. A 3D point cloud is automatically reconstructed from multiview stereo, and is used to compute plausible sky and indirect illumination at each point, despite being sparse. An optimization algorithm estimates sun visibility over the point cloud to compensate for lack
