Handwriting Analysis at CSAFE
This CSAFE webinar was held on March 11, 2021. Presenter: Alicia Carriquiry Distinguished Professor and President’s Chair in Statistics, CSAFE Director Presentation Description: Forensic handwriting analysis relies on the principle
A clustering method for graphical handwriting components and statistical writership analysis
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
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,
CSAFE 2020 All Hands Meeting
The 2020 All Hands Meeting was held May 12 and 13, 2020 and served as the closing to the last 5 years of CSAFE research and focused on kicking off
An Exploratory Analysis of Handwriting Features: Investigating Numeric Measurements of Writing That Are Important for Statistical Modeling
The goal of this presentation is to provide insights into which features of handwritten documents are important for statistical modeling with the task of writer identification and to discuss how
Statistical Analysis of Handwriting: Probabilistic Outcomes for Closed-Set Writer Identification
The goal of this presentation is to provide insights into features of handwritten documents that are important for statistical modeling with the task of writer identification.
A database of handwriting samples for applications in forensic statistics
Handwriting samples were collected from 90 adults for the purpose of developing statistical approaches to the evaluation of handwriting as forensic evidence. Each participant completed three data collection sessions, each
Pattern Evidence Research in CSAFE-An Update
CSAFE is a NIST Center of Excellence in Forensic Science. A large portion of CSAFE’s research portfolio is on what is known as pattern evidence, which encompasses any evidence that
Statistical Analysis of Handwriting for Writer Identification
This presentation overviews the use of a statistical model to provide probabilistic statements of writership for handwritten documents.
