Investigation of Coding Standards Performances on Optically Acquired and Synthetic Holograms

Digital holography needs efficient coding tools that facilitate storage and transmission of this type of data in order to reach practical applications. This paper presents an experimental analysis of the performance of different coding tools for the compression of digital holograms. During the experiments, a dedicated compression architecture is employed in order to transform the holographic data in a representation suitable to be provided to the encoders, and for performing an objective quality evaluation of the obtained results. Several state-of-the-art image and video codecs are evaluated on different reference datasets, comprising different types of digital holograms. The evaluation is carried out on the reconstructed images with different metrics, and obtained results are critically analyzed and discussed.
