Open Source Image De-Noising

Posted by kdawson on from the fuzz-be-gone dept.

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.

  1. And now enhance the image... by blacklint · · Score: 2, Funny

    This looks like it's the closest to the image enhancement on the Enterprise (or any other tv show or movie) that i'm going to come. Very cool! Now to pick out crystal clear faces from distant blurry security cameras...

    ... after those results, I don't want to hear any more bitching about reading yellow license plate numbers off of the reflection of a doorknob reflected in a one-pixel wide eyeball in a black and white security film shown in CSI!

      Really? They shouldn't be complaining.

      Greg Brady did this kind of stuff 30 years ago - when he was in a high school photography class!

    I keep pressing my ear to my computer, but the pictures don't make any noise. They're actually pretty quiet.

    That's because they *removed* the noise, dummy! :]

      Wow, I must have had it installed all along. Except, I think I'm out of space for pictures. I keep sticking more in the slot on the side of the laptop, but no more will fit.

    Christ. The only interface more horrid than MDI is having a bajillion free floating windows that don't have any obvious connection to one another.

    With that, how about GIMP gets USABLE before ya cram in more "features". For a while there I could've sworn you were talking about Photoshop on a mac, my mistake...
