Patent Images
1. A method for processing light field images of a three-dimensional scene, the method implemented on a computer system and comprising:
- accessing an (image,view) domain representation of the light field images of the three-dimensional scene, wherein the (image,view) domain representation of the light field images is a representation of the light field images as a function of (image) and (view) dimensions;
applying a scale-depth transform to transform the (image,view) domain representation to an (image, scale, depth) domain representation, wherein the (image,scale,depth) domain representation is a representation of the light field images as a function of (image), (scale) and (depth) dimensions; and
processing the (image,scale,depth) domain representation of the three-dimensional scene, wherein processing the (image,scale,depth) domain representation comprises at least one of (a) estimating depth in the three-dimensional scene based on processing the (image,scale,depth) domain representation or (b) extracting three-dimensional features in the three-dimensional scene based on processing the (image, scale, depth) domain representation.

Abstract
Light field images of a three-dimensional scene are transformed from an (image,view) domain to an (image,scale,depth) domain. Processing then occurs in the (image,scale,depth) domain.
