Claim One:
1. A method for processing a sequence of holographic images, with a view to its rendition by a holographic display device to at least one observer, wherein, for a holographic image decomposed over a Gabor wavelet basis into a set of wavelet coefficients, the method comprises the following acts performed by a processing device: obtaining items of information representative of the decomposition over the Gabor wavelet basis; obtaining items of information representative of a location of said at least one observer in a reference frame of the display device; the items of information representative of a location of said at least one observer comprising parameters characteristic of a connected and convex subset of positions of the observer, termed an encompassing volume; and selecting a subset of wavelet coefficients as a function of the wavelet items of information and of the location items of information obtained, said selecting comprising the following sub-acts: determining an angular direction of emission and of an angular dispersion of a light cone produced by a Gabor wavelet at a point of the holographic image in a reference frame of the display device; identifying the cones having a non-zero intersection with at least the encompassing volume of said at least one observer; and selecting wavelets corresponding to the identified cones.
