Multi-wavelength holographic image fusions using discrete wavelet transform

We present a fusion method for multi-wavelengths holographic images using Discrete Wavelet transform (DWT). The advantage of DWT is more control on high as well as low frequencies to get better quality. Fusion results include monochromatic fused images and color fused images from holographic images reconstructed from holograms recorded with multiple wavelengths from 567nm to 613nm.
