# Vial PatchCore — Industrial Anomaly Detection

A PatchCore-based industrial anomaly detection model trained for the **Vial** category of the **MVTec AD 2** dataset.

The model is designed to distinguish anomalous vial images from normal vial images and provides an anomaly map for visualizing regions that contribute to the detected anomaly.

## 🚀 Live Demo

Try the deployed model through the interactive Gradio application:

**[Industrial Vial Defect Detection — Hugging Face Space](https://huggingface.co/spaces/pranamjain/industrial-vial-defect-detection)**

Upload a vial image and receive:

- Normal / Defective prediction
- Anomaly score
- Anomaly heatmap
- Visual localization of suspicious regions

## 🧠 Model Overview

### Architecture

**PatchCore**

PatchCore is an industrial anomaly detection approach that represents image patches using deep visual features and compares them against a memory bank representing normal samples.

The model is trained to learn the visual characteristics of normal vial images. During inference, deviations from the learned normal representation produce higher anomaly scores.

## 📊 Evaluation

The trained Vial model was evaluated on the MVTec AD 2 public test set.

| Metric | Score |
|---|---:|
| Image AUROC | **0.7578** |
| Image F1 Score | **0.5315** |
| Pixel AUROC | **0.9142** |
| Pixel F1 Score | **0.1197** |

### Interpretation

**Image AUROC — 0.7578**

The model provides useful separation between normal and anomalous vial images at the image level.

**Image F1 Score — 0.5315**

The F1 score reflects the balance between precision and recall under the evaluation threshold used during the original evaluation.

**Pixel AUROC — 0.9142**

The high pixel-level AUROC indicates that the model can effectively rank anomalous regions relative to normal regions.

**Pixel F1 Score — 0.1197**

The lower pixel-level F1 indicates that precise defect segmentation remains challenging, even though the anomaly map provides useful localization information.

## 🎯 Deployment Threshold

During development, the default image-level threshold resulted in a relatively high number of false negatives for the Vial model.

An additional threshold analysis was performed using the MVTec AD 2 public test set.

The experimental deployment threshold selected for the interactive demo is:
