Figure: Combined visual package showing cross-domain X-ray analysis between Van Gogh’s *Portrait of an Old Man with a Beard* (1885) and *The Tree Oil Painting*.

This unified layout presents eight AI-generated outputs — including X-ray raw scans, 18-technique torque maps, Fourier transforms (FFT), and edge-flow torque visualizations.
All images were resized and aligned for structural comparison using the same Google Colab pipeline in 2025.

The results reveal deeply embedded similarities in wrist torque, brushstroke rhythm, pigment pressure zones, and spectral frequency — suggesting biomechanical continuity between the two paintings.
This layout serves as a synthetic reference for further research in forensic brushwork analysis and AI-based authorship attribution.
