    Abstract: There are several types of plenoptic devices having their proprietary file format. At present there is no standard supporting the acquisition and transmission of multi-dimensional information for an exhaustive over-view of the different parameters upon which a light-field depends. As such acquired light-field data for different cameras have a diversity of formats. The notion of pixel beam, which represents a volume occupied by a set of rays of light in an object space of an optical system of a camera is thus introduced. The method according to the invention enables to provide data representative of a collection of pixel beams describing a first optical system that is agnostic since these data are obtained by imaging the collection of pixel beams through a second optical system. Such data representative of a collection of pixel beams enable the generation of parametrized output images from which post-processing.

    Abstract: A method and an apparatus for generating at least one layered depth image from a set of views representative of a Light-Field capture of a scene are disclosed. Generating the layered depth image comprises segmenting the set of views into groups of pixels, each group of pixels corresponding to light rays imaging a same area in the scene, and generating the layered depth image using the groups of pixels, wherein a first layer of the layered depth image comprises groups of pixels comprised in a reference view from the set of views, and wherein other layers of the layered detph image comprise only groups of pixels that are not comprised in the reference view, and wherein a new layer of the layered depth image is set for a group of pixels from a current reference view if a current layer already comprises a texture at a same position as in the current reference view.
