Abstract
We present a novel phase-based approach for recon-structing 4D lighi field from a micro-baseline stereo pair.Our approach takes advantage of the uaique property of complex steerable pyramid filters in micro-baseline stereo.We first introduce a Disparity Assisted Phase based Synthe-sis(DAPS)strategy that can integrate disparity information into the phase term of a reference image to warp it to it-s close neighbor views.Based on the DAPS,an"analysis by synthesis"approach is proposed to warp from one of the input binocular images to the other,and iteratively op-timize the disparity map to minimize the phase diferences between the warped one and the ground truth input.Fi-nally,the densely and regularly spaced,high quality light field images can be reconstructed using the proposed DAPS according to the refined disparity map.Our approach also solves the problems of disparity inconsistency and ringing artifact in available phase-based view synthesis methods.Experimental results demonstrate that our approach sub-stantially improves both the quality of disparity map and light field,compared with the state-of-the-art stereo match-ing and image based rendering approaches.
