Abstract
Coherent speckle noise is modeled as a multiplicative noise process. Using a logarithmic transformation, this speckle noise is converted to a signal independent, additive process which is close to Gaussian when an integrating aperture is used. Bispectral reconstruction of speckle-degraded images is performed on such logarithmically transformed images when independent multiple snapshots are available.<>
