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...

| description | 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 reconstructed images by filtering. It is demonstrated that the presented method can effectively reduce speckle noise in the digital hologram. |
