## Description

This dataset has been collected by Edge Impulse teams and contains a single fire extinguisher head thread, centered in the frame, with a similar size and a variable background.

The training dataset only contains "good" (no anomaly) images whereas the testing dataset contains both nominal and anomalous images.

### Compatible Blocks

* **Feature extraction**: [Image](/studio/projects/processing-blocks/blocks/image)
* **Learning block**: [Visual Anomaly Detection (FOMO-AD)](/studio/projects/learning-blocks/blocks/visual-anomaly-detection-fomo-ad)

*Not sure what to choose? Try out this dataset with the [EON Tuner](/studio/projects/eon-tuner).*

### Dataset Details

* **Total Data Items:** 204

* **Labeling Method:** single label

* **Train/Test Split:** 58.82% / 41.18%
