Atmospheric icing may be problematic for many industries, including electric utilities. The combination of wind and ice could cause damages, sometimes leading to power outages. The January 1998 ice storm has led to the development of several de-icing methods destined to overhead power lines. These techniques are the subject of several technical reports and publications. Furthermore, in the past...

We present advanced techniques for the restoration of images obtained by soft x-ray laser microscopy. We show two methods. One method is based on adaptive thresholding, while the other uses local Wiener filtering in the wavelet domain to achieve high noise gains. These wavelet based denoising techniques are improved using spatial noise modeling. The accurate noise model is built up from two con...
