Modern holography for 3D imaging allows to reconstruct all the parallaxes that are needed for a truly immersive visualisation. Nevertheless, it represents a huge amount of data which induces higher transmission and storage requirements. To gain more popularity and acceptance, digital holography demands development of efficient coding schemes that provide significant data compression at low computation cost. Another issue that needs to be tackled when designing holography coding algorithms is interoperability with commonly used formats. The upcoming JPEG Pleno standard aims to develop a standard framework for the representation and exchange of new imaging modalities, such as holographic imaging, while maintaining backward compatibility with legacy JPEG decoders. This paper presents a lossy compression method for holographic images that exhibits good coding performance while considering the computation cost and backward compatibility with legacy JPEG standard. To validate our findings, the results of our tests are shown and interpreted.
