Abstract
A method and device are provided for processing images. In one embodiment, the method comprises receiving an image is received of a scene having a plurality of real objects and determining if at least one of these real objects is a reference object stored in a database. Subsequently, candidate shadow map of the reference object identified is retrieved when available and when a reference object cannot be identified, an object in the scene with adequate parameters is selected and the candidate shadow maps of this new reference object using said lighting parameters is computed.
