Adaptive Noise Smoothing Filter for Images with Signal-Dependent Noise
In this paper, we consider the restoration of images with signal-dependent noise. The filter is noise smoothing and adapts to local changes in image statistics based on a nonstationary mean,Expand

Adaptive Restoration Of Images With Speckle
Speckle is a granular noise that inherently exists in all types of coherent imaging systems. The presence of speckle in an image reduces the resolution of the image and the detectability of theExpand
