Reduction of speckle noise in digital holographic images using wavelet transform
The presence of speckle noise in the reconstruction process of digital hologram reduces the signal to noise ratio (SNR) in the reconstructed images. In this paper we present wavelet filtering to improve SNR in the reconstructed images. Experimental results are presented.
