A Super-Duper Image Denoising Algorithm!

"GREYCSTORATION is an image regularization algorithm which processes an image by locally removing small variations of pixel intensities while preserving significant global image features, such as sharp edges and corners. The most direct application of image regularization is denoising. By extension, it can also be used to inpaint or resize images."

It's much better to just go see what GREYCSTORATION can do at the demo page. My jaw dropped. Yours might too!

A very cool invention, indeed.

Yes, it's amazing!

Last two weeks in Numerical Analysis class, there was a presentation on image processing where one of the topics is removing noise by means of Fourier transformation. That's impressive enough for me. :D But this is even amazing. How capable the program is! I notice that many corrected images share the same characteristics--the wavy pattern that looks as if some one has smudged things around.
