Handwriting

A clustering method for graphical handwriting components and statistical writership analysis

February 15, 2021 / Publication / Handwriting

Handwritten documents can be characterized by their content or by the shape of the written characters. We focus on the problem of comparing a person’s handwriting to a document of

Bayesian hierarchical modeling for the forensic evaluation of handwritten documents

December 14, 2020 / Dissertation, Publication / Handwriting

The analysis of handwritten evidence has been used widely in courts in the United States since the 1930s (Osborn, 1946). Traditional evaluations are conducted by trained forensic examiners. More recently,
