Recovering Intrinsic Images using an Illumination Invariant Image

In this paper a method for the extraction of shading and reflectance intrinsic images from a single uncalibrated image is presented. It is based on the classification of the image derivatives as either caused by shading or reflectance effects, using an illumination-invariant image to guide this classification. Our approach avoids the learning process ? which requires ground truth intrinsic images ? and obtain results comparable with the state of the art.
