A model can help localize anomalies, but performance depends on representative data and production conditions.
Visual inspection may use classification, object detection, segmentation, or anomaly-detection methods. Unsupervised anomaly detection can be useful when examples of defects are scarce, but it can also flag normal variation. MVTec datasets provide research benchmarks; their results do not guarantee performance on a particular factory line. A pixel mask is a model prediction, not a confirmed defect or root cause. The 2022 survey paper benchmarks unsupervised anomaly detection and localization methods and discusses inference efficiency. MVTec AD 2 is a separate benchmark with eight scenarios and more than 8,000 high-resolution images, including transparent or overlapping objects, illumination changes, and tiny defects. The paper reports average AU-PRO below 60% for evaluated methods on its benchmark. These scores do not predict performance on a particular factory line.
Flag unusual surface patterns for human review.
Use segmentation to show where a predicted defect may occur.
Run inference near a production line when latency or connectivity requires it.
Validate against labeled samples from the actual process.
Generative methods can augment training data, but synthetic examples must be checked for realism and distribution mismatch. Validate with production data and human quality criteria.

AI-assisted inspection analyzes images or sensor data to flag possible defects. A model can help localize anomalies, but performance depends on representative data and production conditions.
Automated inspection can apply repeatable checks at scale, but detection performance depends on the defect, data, and operating setup.
La detección de anomalías se entrena en muestras normales y señala valores atípicos, para que pueda detectar defectos inesperados sin necesidad de ejemplos etiquetados de cada defecto.
The cited papers evaluate unsupervised anomaly detection/localization, including MVTec AD and the newer MVTec AD 2 benchmark. They do not establish a single architecture as the most common choice for all visual inspection.
A segmentation mask marks model-predicted regions associated with an anomaly. It does not prove a real defect, identify its cause, or replace inspection.
Inference time and throughput depend on hardware, image size, model, batching, and the surrounding line. Measure the target configuration rather than assuming a fixed millisecond guarantee.
