Speckle Reduction in Digital Holography by Fast Logistic Adaptive Non-Local Means Filtering
Digital holography is a promising imaging technology. However, there is speckle noise in the reconstructed image of a digital hologram. Speckle degrades the quality of the reconstructed image. Suppression of speckle noise is a challenging problem in digital holography. A novel method is proposed to...
