Abstract
This study explores the effectiveness of wavelet analysis techniques on digital holograms of real-world 3D objects.
Stationary and discrete wavelet transform techniques have been applied for noise reduction and compared. Noise
is a common problem in image analysis and successful reduction of noise without degradation of content is
difficult to achieve. These wavelet transform denoising techniques are contrasted with traditional noise reduction
techniques; mean filtering, median filtering, Fourier filtering. The different approaches are compared in terms of
speckle reduction, edge preservation and resolution preservation.
