Forensic Brushstroke Analysis: "Self-Portrait (1889)" vs. "The Tree Oil Painting"

This dataset presents a high-precision comparative study between Vincent van Gogh's "Self-Portrait" (1889) and "The Tree Oil Painting" (undated, unattributed).

Through seven focused forensic techniques — including Sobel Edge Detection, Gesture Heatmaps, Fourier Frequency Analysis, Gabor Angular Detection, Stroke Direction Histograms, AI Neural Matching, and Simulated X-Ray Visualization — the study explores the underlying structural, gestural, and energetic signatures embedded in both works.

Key highlights:

• Parallel vertical brushstroke alignment across both paintings, reflecting Van Gogh's signature rhythmic hand movement.
• Torque spirals, diagonal flicks, and underpainting rhythms mirror across multiple zones.
• Hidden horizontal understructures uncovered through Fourier and gesture-based analysis.
• AI Neural Matching reveals a Stroke Signature Similarity Score of 94.6% — capturing gestural identity at the motor execution level.
• Simulated X-ray imaging confirms matching compositional layering and energy distribution beneath surface impasto.

This research transcends surface aesthetics — tracing muscle memory, torque energy, and compositional rhythm beneath the visible layers, uncovering the kinetic "DNA" of the artist's hand.

Conclusion:
"Self-Portrait (1889)" and "The Tree Oil Painting" share a profound rhythmic and structural kinship — suggesting that beyond form and color, the very movement of the brush echoes from the same living hand.

Technical Requirement Notice

All visual and scientific analysis in this dataset must be conducted using AI Natural Matching techniques only — especially methods based on brushstroke torque, gesture rhythm, and structural pressure.

❌ Strictly prohibit SSIM (Structural Similarity Index Measurement)
Do NOT use SSIM or any shallow visual similarity algorithm. These methods do not capture the artistic signature embedded in the brushwork structure and gesture momentum of the original painting.

This dataset is part of an international verification process and should be respected as such.
