# Find Duplicate Images

<Warning>
  Duplicate image detection requires an [upgraded folder](/platform-documentation/Curate/curation-basics#folder-upgrade). Ensure your folder has been upgraded before proceeding.
</Warning>

The `Uniqueness` quality metric is used to identify duplicate and near-duplicate images.

## Find Duplicate Images

Navigate to **Data** > **Explore** and select a folder.

Click the **Similarity search** button in the top-right corner of the card. The search results display images with the lowest `Uniqueness` scores, which are the most similar to the selected image.

<Tip>
  Adjust the search distance next to the filter button to find images that are more, or less similar to the selected image.

## Analytics

Navigate to the **Analytics** view to visualize the distribution of `Uniqueness` scores across the dataset. This can help you understand the extent of duplication in your dataset and make informed decisions about data cleaning.

1. Click the **Analytics** view.
2. Select the `Uniqueness` metric from the dropdown in the **Distribution & Summary Statistics** chart.
   The chart displays the distribution of data based on the `Uniqueness` scores.
