11. An electronic device configured to process a light field image comprising a plurality of views of a 3D scene, the electronic device comprising at least one processor and at least one memory having stored instructions operative, when executed by the at least one processor, to cause the electronic device to:
select a first pixel in a first view of the plurality of views;
generate a first super-ray for the first pixel comprising:
de-projecting the first pixel to identify a corresponding first point in the 3D scene;
re-projecting the corresponding first point in the 3D scene on a second view of the plurality of views to identify a corresponding first pixel in the second view, wherein the second view is different from the first view;
identifying a first set of pixels having a similar color to the corresponding first pixel, wherein each pixel of the first set of pixels is within a first neighborhood of the corresponding first pixel;
group the first set of pixels into the first super-ray.
