    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.

    Abstract: A method for selecting at least one surface in a light field is disclosed. Such a light field is associated with multiple views corresponding to different view points of a same scene. The method comprises:
    - displaying (S402) one of the multiple views as a reference view;
    - selecting (S403) at least one surface in the reference view;
    - identifying (S404) a set of pixels belonging to the selected surface, which are occluded in the reference view but visible in at least one of the multiple views;
    - projecting (S405) the set of pixels into the reference view, on the basis of a value of the pixels of the set in the view or views in which they are visible, in order to form an upgraded reference view;
    - displaying (S406) the upgraded reference view;
    - updating (S407) said selected surface in said upgraded reference view.
