Image Sets

Image Sets are collections of images that can be used for face recognition. You can create an image set for a group of people, such as staff members, or one for each individual.

Requirements

  • Only JPEG images are currently supported.
  • The maximum supported number of images in a single image set is 1000.
  • The maximum supported resolution of an image is 3840 × 2160 pixels (4K).
  • (for Find Faces) Each image should contain exactly one person, facing the camera.

Create an Image Set

  1. Create a folder on your computer (e.g. Staff).

  2. Inside the first folder, create a subfolder for each person (for example: Staff/Employee1). The subfolder name should match the person's name or a term by which they are otherwise identifiable. You can create multiple subfolders within the main folder, one for each individual.

File structure example 
Staff/
├── Employee1/
│   ├── 1.jpg
│   ├── 2.jpg
│   └── ...
├── Employee2/
│   ├── 1.jpg
│   ├── 2.jpg
│   └── ...
└── ...

  1. Put images (multiple are recommended) of the respective entitiy's face into the entity's subfolder: Staff/Employee1 Staff/Employee1/1.jpg

  2. In the web interface, navigate to Assets.

  1. Click on the Add button and select Image set.

  1. Type a name for your image set (e.g. "Staff") and select the folder you created earlier.

  2. Click Save. The image set will be created, and you can see the images in the Assets tab.

Edit an Image Set

  1. Click the image set you would like to edit.

  2. To add images to an entity, click on the menu on its row select Add images to Entity. Upload the folder containing the images you would like to add.

Note that all images in the folder will be added to the entity. Make sure that the folder contains images only for that entity.

  1. To remove an entity, click on the menu button on its row click Delete.

  2. To delete the image set, navigate back to the list of image sets, tick the checkbox of the one you would like to remove Delete Image Set.

Note

Note that currently, an image set can be deleted even if it is referenced by a live query. The live query itself, including existing results, will remain intact, but no new results will be generated.

Using an Image Set in a Query

Image sets can be used in the Find Faces query type to filter for faces in videos. See the Find Faces query's documentation for more details on how to set it up.
