1. A method comprising: receiving N light field (LF) images from which multi-view images can be generated at different angles, and overlapping its adjacent image; selecting a view of a first multi-view image i as a reference for that image; registering and warping views of the first image with the selected reference view; determining parallax error of views as a difference between the warped image and the reference image; and entering the parallax error between the reference view of image i and the multiple views of image(i+1).
