The [ImageBinarization](https://github.com/zygmuntszpak/ImageBinarization.jl) package provides numerous algorithms for transforming an image into a bi-level image (black background and white foreground). The initial release implements the following algorithms:

Some algorithms are particularly well-suited for binarizing text documents. Many of the algorithms are actually implemented in the companion package [HistogramThresholding](https://github.com/zygmuntszpak/HistogramThresholding.jl) which currently operates at the level of one-dimensional histograms and not images.
The package was conceptualized and developed during the _University of Adelaide Summer School Scholarship 2019_ program and includes valuable contributions from:
1. Abbey McCarthy
2. Isabella Scalzi
3. Tristan Betterman
4. Wen Siang Tan
5. Robert Woods
6. William Godfrey
You will find important details about the various algorithms in the package [documentation](https://zygmuntszpak.github.io/ImageBinarization.jl/stable/).
We hope you will find the algorithms useful in your own work.
Best wishes,
Zygmunt Szpak
