Open Source Image De-Noising
GREYCstoration is an open-source tool able to de-noise, inpaint, or resize 2D color images. This is a command-line program developed by the IMAGE team of the GREYC Lab in France and is available for Unix, Mac, and Windows systems under the CeCILL license. The algorithm is based on anisotropic diffusion partial differential equations. These equations are able to smooth an image while preserving its main structures. The demo page presents interesting examples of color image de-noising and reconstruction. This is a serious free alternative to commercial products like Noise Ninja or Neat Image that perform the same kinds of operations. The tool is still a little bit hard to use (command-line based), but I hope the simple C++ API will ease the integration of the algorithm in more user-friendly interfaces. Previous versions of GREYCstoration are already available in Digikam and Krita.
Sorry to break it to you, bud, but not everyone can do everything. You won't catch a legless man running a marathon, nor will you find a tasteless man sipping wine for a living. A deaf man won't be working the drivethrough line at McDonalds, and an armless man wont be MY bodyguard.
Computers are something that exclusively requires sight. It isn't descrimination... it's just a cold fact.

The only thing more pathetic than a PC user is a PC user trying to be a Mac user. We have a name for you people: switcheurs.
There's a good reason for your vexation at the Mac's application-centric, as opposed to task-based, user interface: You don't speak its language. Remember that the Mac was designed by artists, for artists, be they poets, musicians, or avant-garde mathematicians. A shiny new Mac can introduce your frathouse hovel to a modicum of good taste, but it can't make Mac users out of dweebs and squares like you.
So don't force what doesn't come naturally. You'll be much happier if you stick to an OS that suits your personality. And you'll be doing the rest of us a favor, too; you leave Macs to Mac users, and we'll leave beige to you.
