Unified UI and API for processing and training images for facial recognition.
There's a lot of great open source software to perform facial recognition, but each of them behave differently. Double Take was created to abstract the complexities of the detection services and combine them into an easy to use UI and API.
- Responsive UI and API bundled into single Docker image
- Ability to password protect UI and API
- Support for multiple detectors
- Train and untrain images for subjects
- Process images from NVRs
- Publish results to MQTT topics
- REST API can be invoked by other applications
- Disable detection based on a schedule
- Home Assistant Add-ons
- Preprocess images with OpenCV
- amd64
- arm64
- arm/v7
Subscribe to Frigate's MQTT topics and process images for analysis.
mqtt:
host: localhost
frigate:
url: http://localhost:5000When the frigate/events topic is updated the API begins to process the snapshot.jpg and latest.jpg images from Frigate's API. These images are passed from the API to the configured detector(s) until a match is found that meets the configured requirements. To improve the chances of finding a match, the processing of the images will repeat until the amount of retries is exhausted or a match is found.
When the frigate/+/person/snapshot topic is updated the API will process that image with the configured detector(s). It is recommended to increase the MQTT snapshot size in the Frigate camera config.

Trigger automations / notifications when images are processed.
If the MQTT integration is configured within Home Assistant, then sensors will automatically be created.
This notification will work for both matches and unknown results. The message can be customized with any of the attributes from the entity.

Errors from the API will be published to double-take/errors.
