Abstract The ICDAR 2021 Time-Quality Binarization Competition assessed the performance
of 12 new and 49 other previously published binarization algorithms for scanned document …

The intrinsic features of documents, such as paper color, texture, aging, translucency, the
kind of printing, ty** or handwriting, etc., are important with regard to how to process and …

Smartphones with an in-built camera are omnipresent today in the life of over eighty percent
of the world's population. They are very often used to photograph documents. Document …

Image binarization, the conversion of a color image into its monochromatic version, plays a
key role in many document processing pipelines. The technical literature presents over a …

Monochromatic documents claim for much less computer bandwidth for network
transmission and storage space than their color or even grayscale equivalent. The …

The ICDAR 2019 Time-Quality Binarization Competition assessed the performance of
seventeen new together with thirty previously published binarization algorithms. The quality …

Entropy-based image thresholding has received considerable interest in recent years. It is
an important concept in the area of image segmentation. The entropy-based approach was …

Abstract The recent Time-Quality Binarization Competitions have shown that no single
binarization algorithm is good for all kinds of document images and that the time elapsed in …

Image binarization is a technique widely used for documents as monochromatic documents
claim for far less space for storage and computer bandwidth for network transmission than …

Many document processing platforms have image binarization as a key step. The
performance of binarization algorithms depends on several factors that span from the quality …
