Abstract
We present multi-spectral holographic three-dimensional image fusion
using the discrete wavelet transform (DWT). The fusion results are compared
with those of the Gaussian and Laplacian pyramid fusion methods. The advantage
of the DWT over other methods is that it has more flexibility in controlling
high frequency components as well as low frequency components, which improves
the fused image quality. A wavelength tunable solid-state pumped laser is
used to record up to 11 holograms with wavelengths from 567 to 613 nm. We
present the fused reconstructed holographic images including multi-spectral
fused images from the recorded multiple holograms. Fused multi-wavelength
reconstructed holographic images provide multi-spectral information about
the objects.
