Shotwell supports tagging images using faces of persons and assigning a name to them. If enabled, Shotwell also supports automatic detection of faces in images and recognition of already known faces in new images
Double-click on an image in the collection, then press the
Start dragging a rectangle around the face you are tagging using your left mouse button
You can also drag the rectangle by clicking into it or resize it by clicking on one of the borders
Once satisfied, enter a name in the text box below the rectangle and press
Repeat this process for as many faces as you want to mark
After you marked all faces, click on
An existing named face can be either be removed from an image using
To rename the face, use
It is possible to use automatic face detection to simplify the process of marking the faces. To trigger the face detection
algorithm, click on
If reference images for faces are defined, this will also try to match any found faces in the current image with known references.
A named face on a photo can be set as a reference for this particular name. Future calls to the automatic face detection will try to associate similar faces the same name if considered matching.
To declare a face as the reference for its name use these steps
Switch to the face browser by clicking on a face name in the navigation tree.
Select an image that contains the representation of the face you want to make a reference
Click on
By default, Shotwell uses cascade classifier to find faces in images. There is a method to use a deep neural network to improve detection rates significantly, but due to certain uncertainties with the licensing of the trained model it is not included by default.
To enable DNN-based face detection, download the
