Method and apparatus for selecting a surface in a light field, and corresponding computer program product

An apparatus for selecting at least one surface in a light field, said light field being associated with multiple views corresponding to different view points of a same scene, wherein the apparatus comprises:

• one or more processors configured to
• select one of said multiple views as a reference view;
• select at least one surface in said reference view;
• identify a set of pixels belonging to said at least one surface, which are occluded in said reference view but visible in at least one of said multiple views;
• projecting said set of pixels into said reference view, on the basis of a value of said pixels of said set in said at least one of said multiple views in which they are visible, in order to form an upgraded reference view;
• update said selected surface in said upgraded reference view.

A non-transitory computer-readable medium storing program code instructions executable by a processor for selecting at least one surface in a light field, said light field being associated with multiple views corresponding to different view points of a same scene, and for performing operations comprising:

• selecting one of said multiple views as a reference view;
• selecting at least one surface in said reference view;
• identifying a set of pixels belonging to said at least one surface, which are occluded in said reference view but visible in at least one of said multiple views;
• projecting said set of pixels into said reference view, on the basis of a value of said pixels of said set in said at least one of said multiple views in which they are visible, in order to form an upgraded reference view;
