Summary:Recently, there has been a growing interest in the various formats of plenoptic information, including digital holograms. However, the reduced number of studies on holographic data quality assessment results in a difficult analysis of the effects caused by any type of post-processing procedures, like lossy compression. In this work, several state of the art compression codecs, namely HEVC, AV1, and JPEG2000, are applied to the digital holographic data complex representation on the reconstruction plane. Both computer generated and experimental holograms are considered. The perceptual quality of the amplitude is evaluated to measure the quality degradation at four different bit rates. The performance of a selection of quality metrics is also tested.
