Hello Gilles,
I've tested the new plugin for some time now, and I think it is really good,
and certainly better than the old algo. I've not been able to study the
various parameters and to identify a best default setting. This is a tedious
task with so many parameters at hand (for example, after using Refocus
routinely, I have found my optimum default values only now after one year
(which I might suggest for svn, by the way)).
On the other hand I was able to achieve the same quality with the Restoration
plugin, except that it need much more computing time.
Gerhard
