Abstract
A method for processing a sequence of holographic images with a view to playing the images back on a holographic display device to at least one viewer. A subset of wavelet coefficients relevant for the reconstruction of a sub-hologram visible for the at least one viewer from at least one viewing point is selected from a decomposition of at least one holographic image on a wavelet basis and information representative of a location of the at least one viewer in a repository of the display device. In the method, decomposition of the at least one holographic image is carried out on a Shannon wavelet basis.
