Face Recognition¶
To recognize faces, PhotoPrism first extracts crops from your images using a library based on pixel intensity comparisons. These are then fed into TensorFlow to compute 512-dimensional vectors for characterization. In the final step, the DBSCAN algorithm attempts to cluster these so-called face embeddings, so they can be matched to persons with just a few clicks. A reasonable range for the similarity distance between face embeddings is between 0.60 and 0.70, with a higher value being more aggressive and leading to larger clusters with more false positives. To cluster a smaller number of faces, you can reduce the core to 3 or 2 similar faces. It is strongly recommended that you run the "photoprism faces reset" command in a terminal to remove existing clusters and mappings after changing any of the clustering parameters, as otherwise inconsistencies may result in unexpected behavior or errors.
We recommend that only advanced users change these parameters:
| Environment | CLI Flag | Default | Description |

| PHOTOPRISM_FACE_CLUSTER_SCORE | --face-cluster-score | 15 | minimum QUALITY score of automatically clustered faces (1-100) |
| PHOTOPRISM_FACE_CLUSTER_CORE | --face-cluster-core | 4 | NUMBER of faces forming a cluster core (1-100) |
| PHOTOPRISM_FACE_CLUSTER_DIST | --face-cluster-dist | 0.64 | similarity DISTANCE of faces forming a cluster core (0.1-1.5) |
| PHOTOPRISM_FACE_MATCH_DIST | --face-match-dist | 0.46 | similarity OFFSET for matching faces with existing clusters (0.1-1.5) |

-
If you are using Docker Compose, you can open a terminal, run
docker compose stop, and then rundocker compose up -dto restart all services. ↩ -
Enabling public mode is not recommended for instances installed on a server outside your home network, as this allows others to access your pictures without authentication. ↩
