Image Descreening System

A system that removes annoying halftones in scanned images

Target users and customers

Everyone who has to deal with high quality reproduction of halftone images.

Application sectors

  • Heritage scanning
  • Printing


Halftone is a process to reproduce photographs or other images in which the various tones of grey or color are produced by variously sized dots of ink.

When a document using this process is scanned, a very uncomfortable screening effect may appear.

The system uses a combination of removal of peaks in Fourier image and local Gaussian blur.
