Compression of Digital Holographic Data

Abstract

Both lossless and lossy compression methods have been attempted in compressing digital holographic data. In the early phase, the performance of lossless coding and quantization methods were mainly investigated, while recent research works are more focused on lossy compression with wavelets transform, as summarized in this chapter.

In the second part, we discuss in more detail several wavelet-based holographic data compression methods based on Fresnelet (Liebling et al., 2003; Darakis and Soraghan, 2006a), separable and nonseparable vector lifting schemes (Xing et al., 2014a, 2015), arbitrary packet decomposition and directional wavelet transform (Blinder et al., 2013, 2014), and Morlet ...
