Facial alignment

📖 Full definition

Before computing an embedding, the face is aligned: rotation so the eyes are horizontal, centred crop, standard scaling. Without this step, two photos of the same person at different angles would produce very different embeddings.

💡 Concrete example

If your photo is slightly tilted, facial alignment straightens it before analysis — otherwise the resemblance score would drop artificially.
