Abstract
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. A holographic image is decomposed over a Gabor wavelet basis into a set of wavelet coefficients. The method includes the following acts, implemented for an image of the sequence: obtaining items of information representative of the decomposition over the Gabor wavelet basis; obtaining of items of information representative of a location of the at least one observer in a reference frame of the display device; selecting a subset of wavelet coefficients as a function of the wavelet items of information and of the location items of information obtained.
