# Detect and Organize People

> Run face detection on your sources, cluster detected faces into groups, create named Persons, and browse files where a specific person appears in your library.

The **People** feature uses face detection and machine learning to find faces across your photo and video library, group similar faces into clusters, and let you assign names to those clusters. Once a person is named, you can browse every file in your catalog where they appear. People is currently in beta.

<Warning>
  People is a beta feature. Results may be incomplete or imprecise, particularly
  for low-resolution images, partially obscured faces, or large libraries with
  significant variety in lighting conditions.
</Warning>

## Step 1: Detect people on a source

Face detection must be run on each source before faces from that source appear in the People page. You run detection from the source in the file browser, not from the People page itself.

<Steps>
  <Step title="Open a source">
    Click a source in the **Sources** tab to open it in the file browser.
  </Step>

  <Step title="Run face detection">
    Right-click the source name in the sidebar, or click the options menu on
    the source, and choose **Detect People**. You can also select individual
    files in the browser, right-click, and choose **Detect People** to run
    detection only on those files.
  </Step>

  <Step title="Wait for detection to complete">
    Detection runs in the background. For large sources with many images and
    videos, this may take several minutes. You can continue using 1Archive while
    detection runs.
  </Step>
</Steps>

<Note>
  Face detection works on both photos and video files. For videos, 1Archive
  samples frames throughout the clip and detects faces in each sampled frame.
</Note>

## Step 2: Cluster detected faces

After detection, the raw face data exists but has not yet been grouped into clusters. Clustering is the process that groups similar-looking faces together so that all appearances of the same person end up in one cluster.

<Steps>
  <Step title="Open the People page">
    Click **People** in the sidebar (labeled with a BETA badge).
  </Step>

  <Step title="Click Cluster Faces">
    Click the **Cluster Faces** button at the top of the page. A status message
    appears while clustering runs.
  </Step>

  <Step title="Wait for clustering to complete">
    Clustering analyzes all detected faces across your library and groups them
    by visual similarity. When complete, a success message appears and face
    clusters populate the page.
  </Step>
</Steps>

<Tip>
  Run **Cluster Faces** again after detecting people on additional sources to
  incorporate new faces into the existing clusters. Previously named persons are
  preserved, new faces are merged into existing clusters or grouped into new
  ones as appropriate.
</Tip>

## View face clusters

After clustering, the People page displays a grid of face thumbnails. Each card represents one cluster, a group of faces that 1Archive determined likely belong to the same person. Each card shows:

* The **cover photo** for the cluster, the highest-quality face detection in the group.
* The **person name**, if the cluster has been assigned to a named person, or "Unknown" if not.
* The **face count**: how many individual face detections are in the cluster.

Click a cluster card to open all the files in your library where that cluster's faces appear.

## Create a named person from a cluster

<Steps>
  <Step title="Select an unassigned cluster">
    On the People page, click a cluster card that shows "Unknown". The card
    highlights to indicate it's selected.
  </Step>

  <Step title="Click Create Person">
    Click the **Create Person** button in the action bar at the top of the page.
  </Step>

  <Step title="Enter a name">
    Type the person's name in the dialog that appears and click **Create**.
  </Step>
</Steps>

The cluster is now associated with that person's name and appears with their name in the grid. All future clustering runs will assign new matching faces to this person automatically.

## Add a cluster to an existing person

If you have two or more clusters that represent the same person, you can merge them by adding one cluster to an existing person.

<Steps>
  <Step title="Select the cluster to merge">
    Click the cluster card you want to assign. It must not already be assigned
    to a person (the name shows "Unknown").
  </Step>

  <Step title="Click Add to Person">
    Click the **Add to Person** button in the action bar.
  </Step>

  <Step title="Choose the person">
    Select the target person from the list in the dialog and click **Add**.
  </Step>
</Steps>

## Change a person's cover photo

The cover photo is the face thumbnail that represents a person on the People page. 1Archive selects the highest-quality detection automatically, but you can change it.

<Steps>
  <Step title="Select a named person">
    Click the cluster card for the person whose cover you want to change.
  </Step>

  <Step title="Click Change Cover">
    Click the **Change Cover** button in the action bar. A dialog shows the top
    face detections for that person.
  </Step>

  <Step title="Choose a new cover">
    Click the face image you want to use as the cover and click **Set as
    Cover**.
  </Step>
</Steps>

## Delete a person

Deleting a person removes the name assignment from the cluster but does not delete the underlying face detections or the files themselves. The cluster returns to "Unknown" status.

Select a named person's cluster card, then click **Delete Person** in the action bar and confirm the deletion.
