POPULATION DISTRIBUTION

Empirical baselines across 328 autographs

Before computing similarity between any two signatures, each raw measurement is standardized using the population mean (μ) and standard deviation (σ) across the collection:

DimensionWhat it measuresPopulation Mean (μ)Std. Deviation (σ)Graphological interpretation focus
Slant angle (°)Dominant downstroke angle relative to vertical16.9°18.6°Emotional expressiveness vs controlled reserve

How we compute signature similarity

STEP 01 · EXTRACTION

9-Vector Geometry

Every signature is traced into skeleton strokes, bounding envelopes, slant ticks, enclosed loop counters, and baseline trajectories.

Vector Skeleton

STEP 02 · SCALING

Z-Score Normalization

Log-transforms stabilize skewed ratios (aspect and pen lifts) before converting all 9 dimensions into dimensionless z-scores.

z = (x − μ) / σ

STEP 03 · DISTANCE

Euclidean Distance

We compute the 9-dimensional Euclidean distance d(A,B) between the two standardized z-vectors and map it to a 0–100% score.

Score = 100 − 18·d

STEP 04 · WORKBENCH
