The quality of document images may have faded during the document life cycle.
The noise degrades image quality and makes further image processing and analysis
more difficult. Even though human eyes and modern OCR systems can tolerate some
level of noise, it still introduces unnecessary details that weaken compression
performance. Image enhancement is aimed at eliminating noise degradation and
improving image compression performance, while still preserving image quality.
