Description

The function face_recognition.api.face_distance returns the euclidean distance between a given face encoding and a list of encodings.

The result of all the distances are between 0 and 1. Why is the maximum distance 1?

Thanks in advance

Research direction

Start with the face_recognition.api.face_distance entry point and inspect how face encodings and Euclidean distances are defined. Establish whether the observed 0–1 range is guaranteed by the implementation or only typical for these encodings, then document a clear explanation of the result and its limits.
