# MVTec Anomaly Detection Dataset (MVTec AD)
## Dataset description
The **MVTec Anomaly Detection (MVTec AD)** dataset is a large-scale real-world dataset for unsupervised anomaly detection in industrial inspection scenarios.
It contains high-resolution images of multiple object and texture categories, including normal samples and various defect types with pixel-level ground truth masks.
Official website:

## Dataset format
In this repository, the dataset is provided as a **single compressed archive**:
**`mvtec_anomaly_detection.tar.xz`**
After downloading, the archive must be extracted locally:
```bash
tar -xJf mvtec_anomaly_detection.tar.xz
```

## Dataset structure
```text
Each category follows the structure:
category/
├── train/
│ └── good/
├── test/
│ ├── good/
│ └── defect_type/
└── ground_truth/
└── defect_type/
```
- Training set: only normal images
- Test set: normal and anomalous images
- Ground truth: pixel-level defect masks
---
## Categories
The dataset includes objects and textures such as:
bottle, cable, capsule, carpet, grid, hazelnut, leather, metal_nut, pill, screw, tile, toothbrush, transistor, wood, zipper, and others.
