Abstract
Penumbral images of neutron distributions form laser fusion experiments provided by large aperture imaging systems are degraded by signal-dependent noise. Most image processing algorithms assume that the signal and the noise are stationary. The purpose of this paper is to introduce a new approach using a locally adaptive non-stationary filter. This method modifies the stationary Wiener filter approach by trading off noise removal against resolution. We shall describe the method and show some results.
