Abstract
The present disclosure concerns a method for processing a light field image comprising a set of image views. The method is remarkable in that it comprises: selecting () a set of pixels, named centroids, within a given image view in said light field image, each centroid being associated with a unique label and a unique light ray; de-projecting said centroids, that delivers a set of points in a 3D space; re-projecting said points of said set of points in a 3D space in at least one other image view in said light field image, which is different from said reference view, that delivers a set of re-projected centroids; and determining (), for each pixel, being associated with a light ray, within a neighborhood of a re-projected centroid, a label related to one of the centroids, said determining relying on a proximity criterion in term of color between pixels and centroids, and a proximity criterion in term of spatial distances between pixels and re-projected centroids; and updating (), for a given centroid, a color value associated with said given centroid, and spatial coordinates of said given centroid within said given image view, wherein said updating comprises: de-projecting pixels in said at least one other image view that are associated with a same label of said given centroid, delivering a set of obtained points; and re-projecting said obtained points into said given image view, delivering a set of projected points; and averaging both color values associated with said projected points and spatial coordinates associated with said projected points for defining updated information related to said given centroid.
