SVN commit 535025 by cgilles:
digikam from trunk : NoiseReduction tool : patch from Peter Heckert :
1./ Set default radius to 5.0.
Reason: previous default value 1.0 has almost no effect for typical noise.
Value 5.0 is good for medium noise in almost all cases.
That does not mean, that always radius 5 is used, because radius is
dynamically adapted while filtering.
This means that radius /can/ grow until 5.0. The amount of growing
depends from "threshold" setting.
That is: /Maximum/ radius is 5.0.
This value is good for the "baby.jpg" image that I almost use for testing.
2./ Interchanged "Sharpness" and "Lookahead".
3./ Cleaned up some "Whats this?" hints for briefness and clarity. ==> To update handbook too !!!
