摘要：
An analysis and discussion on the relevance of various wavelet schemes for hologram compression and reconstruction when the rendering con figuration makes it possible to exploit selective refinements to perform a viewpoint-based degraded reconstruction. It is observed that Gabor wavelet bases have better time-frequency localization as compared to Fresnelet bases and hence are well suited for view-dependent compression techniques for hologram reconstruction.
