NORMALIZATION

Z-Score Standardization

Each geometric measurement is normalized against our population baseline of 328 catalog autographs to eliminate arbitrary scale differences.

μ & σ Scaling

EUCLIDEAN DISTANCE

Multidimensional Similarity

We calculate Euclidean distance across all 9 dimensions, transformed into an intuitive 0–100% geometric shape similarity score.

GRAPHIC SILHOUETTE

Structural Proportions

Underlines, loop counts, opening capital scale, and width-to-height ratio define the overarching visual silhouette.

Envelope Alignment

INTERPRETATION

Graphological Contrasts

Dynamic analysis synthesizes where the specimens harmonize in baseline or slant, and highlights core stylistic deviations.
