The examples on the web show a substantial improvement. This single image can then be sharpened using wavelet processing to further improve the image. An AVI file obtained by a web cam for instance is a collection of jpg’s and these jpg’s can be processed by Registax to obtain a single high quality image. These techniques allow astronomers to obtain high quality images of planets, stars etc using relatively cheap equipment. Registax is a free program used by astronomers to stack, align and average multiple images such as would come from a web cam. There is a steep learning curve, and it is not well documented (for photographers). I have been playing around with Registax for a number of years to sharpen images.
