Given a set of low resolution camera images of a Lambertian surface, i
t is possible to reconstruct high resolution luminance and height info
rmation, when the relative displacements of the image frames are known
. We have proposed iterative algorithms for recovering high resolution
albedo with the knowledge of high resolution height and vice versa. T
he problem of surface reconstruction has been tackled in a Bayesian fr
amework and has been formulated as one of minimizing an error function
. Markov Random Fields (MRF) have been employed to characterize the a
priori constraints on the solution space. As for the surface height, w
e have attempted a direct computation without refering to surface orie
ntations, while increasing the resolution by camera jittering.
