Class ForgeryDetector

java.lang.Object

org.episteme.social.arts.ForgeryDetector

public final class ForgeryDetector
extends Object

Provides statistical analysis tools for art forgery detection. It analyzes brushstroke patterns and compares them against known artist statistical fingerprints using z-score analysis.

Method Details

calculateProfile

public static ForgeryDetector.BrushstrokeProfile calculateProfile(List<double[]> strokes)

Calculates a summary brushstroke profile from raw stroke measurements.

Parameters:

strokes - raw measurements: {length, width, pressure, direction, curvature}

Returns:

a consolidated BrushstrokeProfile

authenticityScore

public static Real authenticityScore(ForgeryDetector.BrushstrokeProfile sample,
 ForgeryDetector.ArtistFingerprint fingerprint)

Computes an authenticity confidence score (0 to 1) for a sample work against a known artist fingerprint.

Parameters:

sample - the profile of the work being examined

fingerprint - the verified fingerprint of the artist

Returns:

confidence score as a Real number

detectAnomalies

public static List<String> detectAnomalies(ForgeryDetector.BrushstrokeProfile sample,
 ForgeryDetector.ArtistFingerprint fingerprint)

Identifies specific metrics that deviate significantly from an artist's typical technique (e.g., "hesitation marks").

Parameters:

sample - the profile of the work being examined

fingerprint - the verified fingerprint of the artist

Returns:

list of detected anomalies
