Holding unseen connector assemblies as anomalies
An unlabelled connector assembly arrangement can appear. Instead of forcing the new type into a known defect label, show its local difference from the normal layout.
Link the departure-from-normal score and pin region to the sample identity without automatically naming the assembly issue. Hold the specimen in the review nest.

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 nominal pin layout and compare new ROI features with the normal gallery. Localise the unusual pin island on the heatmap.
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.
