Face quality
Most failed verifications are capture problems. Quality checks catch them early and tell the person what to change.
| Reason | Meaning |
|---|---|
| no_face | No face was found |
| multiple_faces | More than one face was found |
| face_too_small | The face is too small |
| too_blurry | The face isn't sharp |
| too_dark, too_bright | Lighting is out of range |
| low_contrast | Flat or hazy lighting |
| pose_yaw, pose_pitch, pose_roll | The head is turned too far |
These limits are provisional and will be tuned on reviewed pilot captures. They measure the image, never the person.
