nonlinear diffusion equation for image restoration is introduced, and then an edge indicator is showed in the final update equation to constrain the image edge, staying as close as possible to the input image and to restore discontinuities, which improve the ability of speckle noise removal. Compar...

So, here speckle noise is considered for modeling the noise during transmission, Gaussian noise during scanning procedures considering the thermal radiations of the scanning mechanism, and the salt and pepper noise (impulse valued noise) for representing the aging phenomenon. To eliminate a certain ...

The method of speckle reduction is widely used in synthetic aperture radar (SAR) imagery over the last three decades. The SAR images are inherently speckled in nature. Speckle noise is a granular pattern distribution, usually modeled as a multiplicative noise that affects the SAR images, as well...
