Irregular texture deviations in glass sealing beads
An irregular local sealing texture on glass may remain within usual geometry limits. Detecting departure from normal appearance differs from proving sealing performance.
Record the bead anomaly location and raw image for review and hold it on appearance only. Neither leak-test nor adhesion results are inferred.

Solution approach
Local features of normal examples are compared with the new ROI. Raw evidence, normal reference and a continuous anomaly map appear separately; the score threshold is not a defect class. Register the bead path and show normal bead patches beside the new sample. Compare the local texture score with the decision threshold.
Process steps
- 01
Normal reference
Select the illustrative reference gallery of normal examples only.
- 02
New image
Image the new sample under the same lighting and registration conditions.
- 03
Local comparison
Show local feature deviation as a continuous heatmap.
- 04
Score threshold
Show the local score and above-threshold area as separate criteria.
- 05
Send for review
Hold an anomalous example for the operator without inventing a defect type.
