The (Automated Letter Feature Analyzer) ALFA website is a collection of tools and resources for collecting glyph images, labeling machine learning datasets, and analyzing glyph anatomy. The site is part of a larger effort at the University of Nebraska - Lincoln to decipher a handful of ancient scripts.

You can view a large number of scripts both ancient and modern in various typefaces on the scripts page, and download a .zip file containing an image of each glyph on the downloads page. The labeler page is built to efficiently label images for machine learning datasets. Users can upload glyph images to the analyzer to have their features extracted by the system. You can learn more about using ALFA on the tutorial page.
