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

Document image binarization is a fundamental step in many document processes. No
binarization algorithm performs well on all types of document images, as the different kinds …

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 …

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 …

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 …

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

Binarization algorithms are an important step in most document analysis and recognition
applications. Many aspects of the document affect the performance of binarization …

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 …
