                         process based on the correspondence between pairs of photometric 
                         stereo images, from which a photometric disparity map can be 
                         obtained which encodes surface curvature information. Here we 
                         formulate a linear approximation to DBPS through the linearization 
                         of the reflectance map function, which is the function relating 
                         image intensities to surface orientation. We show that linear DBPS 
                         allows the recovery of relative depth from the photometric 
                         disparity map, and illustrate our approach in simple experiments
