How the match is worked out

  1. Find the face

    A detector scans each photo and boxes every face. If there are several, the largest one is used.

  2. Map 68 points

    A second model places 68 points on the face: 17 along the jaw, 10 on the eyebrows, 9 on the nose, 12 around the eyes and 20 around the mouth.

  3. Overall score

    A face-recognition model turns each face into a fingerprint of 128 numbers. The baby's fingerprint is compared with each parent's, and the closer one wins. The percentages show how much closer, not how identical: 62% means "nearer to this parent than the other".

  4. Feature by feature

    Each face is straightened and rescaled so the eyes are level and the same distance apart. Then the shape traced by the points of each feature on the baby is compared with the same feature on each parent. Eyebrows are measured relative to the eye below, so their height counts too.
