Face → Embedding → Decision
A face encodes to 512 numbers. Two embeddings get a cosine similarity score. A tuned threshold decides accept or reject.

Raw embeddings
Each face is compressed into 512 numbers by ArcFace (ResNet-100). The heatmap below shows the full vector — warm = high, cool = low. Similar faces produce similar patterns; different people produce visibly different signatures.

Move the slider to see how the threshold trades off false accepts (impostors accepted) vs false rejects (genuine users turned away).
