Independent component analysis applied to digital holograms of three-dimensional objects

Speckles removal in digital holography using multiple wavelengths/distances from an object

“…By use of wavelet decomposition, threedimensional image fusion has been proposed and some speckles reduction has been achieved [1,2]. Independent component analysis has been also applied to reduce speckles [3]. Somewhat speckle noises has been reduced by the approach.…”

Image Quality Improvement of Digital Holography by Multiple Wavelengths or Multiple Holograms

“…This is why the reconstructed image has noticeable speckles. To reduce the speckles, some signal processing approaches have been proposed Do et al, 2005;Maycock et al, 2005;Kreis & Schlüter, 2007). By use of wavelet decomposition, three-dimensional image fusion has been proposed and some speckles reduction has been achieved.…”
