Abstract
We present multifocus holographic 3-D image fusion based on independent
component analysis (ICA). In this paper, the ICA technique is used to fuse
multiple reconstructed holographic images at different distances from the
image sensor. A hologram of two dice located at distances of 315 and 345 mm,
respectively, from the sensor is recorded using phase-shifting digital holography
and used in our experiments. The resulting reconstructed fused holographic
image shows both dice objects clearly in focus. This is compared with a single
reconstructed holographic image in which only one of the die objects is in
focus at a particular reconstruction distance.
