Abstract
For 3D Lambertian scenes with no occlusion, we show that there exist a filter bank such that it can perfectly reconstruct the light field from the focal stack, if the focal stack is captured through “Cauchy-type” aperture mask. All the derived filters are spatially invariant; therefore the presented filter bank method requires no depth estimation. Simulation results using a synthetic scene show that the filter bank reconstructs the light field with significant high quality.
