Speckle Reduction of Reconstructions of Digital Holograms Using Gamma-Correction and Filtering
Speckle noise is inevitable in the process of acquiring of digital holograms. In this paper, a new approach is proposed to suppress the speckle noise in the digital hologram. The method is composed of two steps: 1) to enhance the noisy digital holograms by Gamma correction, and 2) to process the rec...
