Physics-Inspired Scatter Correction Improves Defect Visibility in Industrial Radiography

A physics-inspired scatter removal framework improved contrast-to-noise ratio to 2.94 and achieved lower image quality scores (NIQE 4.67, BRISQUE 22.37) on 60 weld radiographs, outperforming conventional enhancement methods.

• Evaluated on 60 industrial weld radiographs (ship plates, boilers, oil pipelines).
• Ablation studies confirmed incremental benefits of each pipeline stage; sensitivity analyses demonstrated robustness across weld categories and parameter changes.
• Limitation: empirically calibrated coefficients, not derived from first principles; cross-dataset generalization remains untested.
