A ghost imaging framework based on laser mode speckle pattern for underwater environments
Communications EngineeringDue to the complex physical processes found in underwater environments, such as absorption, scattering, and noise, it is challenging to obtain high-quality images using conventional camera-based imaging techniques.

Reduction of speckle noise by using an adaptive window
, 2012 Speckle noise is a multiplicative noise that results from random fluctuations of signals when they are reflected on a surface. This research article proposes a techniqueto reduce speckle noise by using classic statistical filters and a size-adaptivewindow.
