Search for similar face

Face search allows you to find faces similar to a given photo in an archive.

When searching for faces in the video surveillance window, the face track and its dimensions are always highlighted.

To perform face search:

1. Set the search interval (see Setting a search interval).

2. Set the minimum similarity level (in %) between the face in the photo and faces from the archive (1). The search results will contain only the video footage with faces with similarity levels above the set value.  
   

3. Select a photo with the face to be searched for in the archive (2). Supported formats: png, jpg, jpeg, jpe. Clicking on a face will select this face as a search parameter. If you do not select a photo, then all faces recognized during the specified time will be displayed. To delete a photo from the search, click .

4. Select, how to sort search results:  - by the face match;  - by time (3).

5. If necessary, set additional search criteria by clicking the button:

   1. Gender: select the required option;

   2. Age span: specify in years in From and To fields.
      

      Note

      Saving information about gender and age to the database should be enabled in the detection tool settings (see Configuring Face detection).

      To delete a criterion, click the button.

6. Click the Search button.

   Note

   Once launched, the search can be stopped at any time. To do this, click the Stop button which appears instead of the Search button.

This starts a search in the archive based on the defined criteria.

The video frames with faces satisfying search conditions will be displayed in the search results panel. A recognized face will be highlighted with a red frame, and the face similarity level (in %) will be shown below.

To instantly export a face image from the scene, do the following:
