SHADOW-BASED ESTIMATION OF 3D LIGHTING PARAMETERS FROM REFERENCE OBJECT AND REFERENCE VIRTUAL VIEWPOINT

摘要

A method and device is 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 identifiled, 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.
