ReikaChan said: I recently discovered a neat little script http://waifu2x.udp.jp/ and it literally blew my mind! The quality of the script is just out of this world. It is able to remove jpeg artefacts and resize pictures by the factor of 2. However, it preserves an incredible amount of fine details, I have never seen before.
I have used it to clean up two jpeg_artifacts tagged posts to demonstrate what I mean. The code is open source and many different projects exist around it. I'm sure some of you already know this, but for everyone else, this is the swiss knife you need for picture cleanup!
Woah, never tried the noise reduction part. It's so good. Which level do you use, low or high?
And yeah, it only works with very high frequency noise (like jpeg artifacts, or screening on resized scans). It won't work with screening in 300dpi and above.
