Abstract

Archiving of image data often requires a suitable data reduction to minimise the memory requirements. However, these compression procedures entail compression artefacts, which make machine processing of the captured documents more difficult and reduce subjective image quality for the human viewer. A method is presented which can reduce the occurring compression artefacts. The corrected image yields as output of an auto-associative memory that is controlled by a Self-Organising Map (SOM).
