01 — Static · ISO/IEC 17025
Handwriting Static Analysis
A statistically rigorous, court-defensible framework that compares handwriting samples of unknown origin and produces a calibrated Score-Based Likelihood Ratio (SLR) using graph decomposition and a Random Forest ensemble trained on a certified forensic handwriting database.

02 — Dynamic · ISO/IEC 19794-7
Handwriting Dynamic Analysis
A concurrent multi-style comparison engine that analyses several handwriting styles simultaneously and ranks them by quantitative similarity score — capturing scribal hand characteristics, style drift over time, and neuromuscular behavioural patterns.

Detect Signature
A Vision Transformer (ViT) fine-tuned with DETR bipartite matching loss — applies global self-attention across the full document to precisely locate handwritten signature bounding boxes. Trained on 2,819 labelled document images from real-world forensic corpora.
