Anomaly screening of embossed characters inside wheels
Embossed characters inside a wheel appear together with casting texture, viewing angle and reflections. Separating unusual character shape from ordinary surface texture requires evidence tied to the product family.
Proposed output: suspicious character region and the reference used for comparison. This concept derives from a historical need and does not claim a delivered or accepted installation.

Solution approach
Align the inner-character region to the product reference and compare illumination images in the same ROI. Evaluate the AI anomaly map against normal character examples and region masks. Use a review route instead of a defect decision when identity is uncertain.
