|+||====== Video filter asharp ======|
|+||asharp is an adaptive sharpening filter and was written by [[http://ziquash.chez-alice.fr/|MarcFD]]. The filter is based on the popular Unsharp Masking, a very powerful method of sharpening. But in contrast to simple Unsharp Masking, asharp allows adaptive sharpening. This means asharp can sharpen the video without amplifying noise! Note that this filter has been optimized for quality, not speed.|
