Classification: CPC G | IPC G  H

Claim 0:
1. A method of processing light field images, comprising:
capturing a plurality of views at a plurality of viewpoints with different polarization angles;
obtaining an initial disparity estimation for a first view using SIFT-flow, and warping the first view to a reference view;
optimizing an objective function comprising a transmitted layer and a secondary layer using an Augmented Lagrange Multiplier (ALM) with Alternating Direction Minimizing (ADM) strategy;
updating the disparity estimation for the first view;
repeating the steps of optimizing the objective function and updating the disparity estimation until the change in the objective function between two consecutive iterations is below a threshold; and
separating the transmitted layer from the secondary layer using updated disparity estimation for the first view.
