Compression of digital holograms is a major challenge that needs to be resolved to enablethe efficient storage, transmission and rendering of macroscopic holographic signals. Inthis work, we propose to deploy the wave atom transform that has been utilized before forinterferometric modalities such as acoustic and seismic signals. This non-adaptive multi-resolution transform has good space-frequency localization and its orthonormal basis issuitable for sparsifying holographic signals. By replacing the CDF 9/7 wavelet transformstage in a JPEG 2000 codec with the proposed wave atom transform, we did assess itssuitability for coding complex amplitude wavefronts. Experimental results demonstrateimproved rate-distortion performance with respect to JPEG 2000 and H.265/HEVC for aset of computer-generated, diffuse, macroscopic holograms.
