Resolution-enhanced reconstruction of far 3-D objects by using a direct pixel mapping method in computational curving-effective integral imaging

In this paper, we propose a novel approach for resolution-enhanced computational reconstruction of far 3-D objects by employing a direct pixel mapping (DPM) method in the curving-effective integral imaging (CEII) system. In this method, by using the DPM method, an elemental image array (EIA) picked up from a far 3-D object can be computationally transformed into a new EIA, which virtually looks like the EIA picked up from a near object. Therefore, with this newly transformed EIA a much better resolution-enhanced object image can be reconstructed in the CEII system. Good experimental results confirmed the feasibility of the proposed method.
