Optimal watermarking of digital hologram of 3-D object
Hyun Kim, Yeonho Lee · Optics Express · 2005
The optimum condition for watermarking the digital hologram of a 3-D host object is analyzed. It is shown in the experiment that the digital hologram watermarked with the optimum weighting factor produces the least errors in the reconstructed 3-D host object and the decoded watermark even in the presence of an occlusion attack.
