Speckle noise reduction techniques for high-dynamic range imaging [PDF]
ComptesRendusPhysique8:349-354,2007, 2007 High-dynamic range imaging from space in the visible, aiming in particular at the detection of terrestrial exoplanets, necessitates not only the use of a coronagraph, but also of adaptive optics to correct optical defects in real time. Indeed, these defects scatter light and give birth to speckles in the image plane.

On the extension of multidimensional speckle noise model from single-look to multilook SAR imagery [PDF]
, 2007 Speckle noise represents one of the major problems when synthetic aperture radar (SAR) data are considered. Despite the fact that speckle is caused by the scattering process itself, it must be considered as a noise source due to the complexity of the ...
