Resemblance Score Explained
When Related Faces compares two faces, it assigns each potential match a Resemblance Score, a percentage that indicates how visually similar the two faces are.
What the Score Means
98–99% means the faces are extremely close, often the same person
95–97% is a strong resemblance, but could be a close relative
Below 95% may still be accurate, especially if photos vary in age or angle
📌 High resemblance does not always equal a match, lighting, age difference, and quality can impact score accuracy.
Why Scores Vary
Several factors influence the resemblance score:
Photo quality — sharpness, lighting, and resolution
Face angle or tilt — side profiles usually score lower
Age differences — baby vs. adult photos may result in lower scores
Facial expressions — smiles, squints, or shadows can skew results
Use the Score as a Guide
Think of the score as a starting point, not a final decision. Your insight is what confirms or rules out a match.
When in doubt:
Click the face to see the full photo
Compare it to other known faces in the same profile
Use the Uncertain option if you’re not ready to commit
🧠 Human judgment is critical, the system is powerful, but it improves most when real people make thoughtful decisions.
