Handwriting Analysis Tool
HAT is a software tool that can be used to analyse handwriting styles. Several different handwriting styles (scribal hands) can be analysed concurrently and sorted according to their similarity to a questioned or unknown style (query). A similarity score will be calculated for each predefined style (scribal hand) to create a relative comparison between them with respect to an unknown style.
The handwriting styles (scribes) do not need to be known, only discriminative labels must be used for each different style (hand).
This tool is being developed by Hussein Mohammed, researcher in sub-project Z03 of CSMC at Universität Hamburg and is based on the method presented in the following publication:
- Mohammed, V. Märgner, T. Konidaris, and H. S. Stiehl, “Normalised local näive bayes nearest-neighbour classifier for offline writer identification”, in 2017 14th IAPR International Conference on Document Analysis and Recognition (ICDAR). IEEE, 2017, pp. 1013–1018.
HAT uses the EMGU library, which is free for open source software and for non-commercial usage.
HAT also uses Scale Invariant Feature Transform (SIFT) algorithm which is patented in the U.S., but it requires to buy a license only for commercial software.

The .zip file includes:
- a Windows installer that works for both x32 and x64 platforms (MacOS via a virtual machine or Wine)
- a manual that provides a description of the directory structure, usage procedure and some necessary remarks.
