Abstract
In one embodiment, it is proposed a method for encoding a light field content. The method is remarkable in that it comprises: —obtaining, for a set of light rays (401) associated with said light field content, four coordinates per light ray from a two planes parametrization (2000; 402, 403) of said light field content; —obtaining (2001), for each light ray from said set, two coordinates from said four coordinates, corresponding to a projection of said light rays from said set onto a plane (404, 405, P) perpendicular to two planes used in said two planes parametrization, defining points in a first 2D ray diagram (Π(χ1, χ2), Π(χ1, χ2)); —applying (2002) a discrete Radon transform on said first 2D ray diagram (Π(χ1, χ2), Π(χ1, χ2)) that delivers lines of interest in said first 2D ray diagram; —encoding (2003) said lines of interest into encoded lines of interest; and—storing (2004) said encoded lines of interest.
