1. A method, comprising:
accessing a plurality of images captured by one or more cameras, wherein said images represent a plurality of views corresponding to a same scene;
generating a plurality of plane sweep volume (PSV) slices from said images and computing for each slice a displacement map from calibration parameters of the one or more cameras, wherein PSV slices, corresponding to one reference camera, are located at successive depth planes in a coordinate system of said one reference camera; and
using this displacement map to generate at least one of a next and a previous slice of the plane sweep volume.
