Perspective Face Correction maps the full shape of the face in detail and double-checks it against the separately located eyes, nose, and mouth. It compares three separate signs of a turned head—how far the nose sits off center, the visible width of each cheek, and the estimated depth of each cheek—and proceeds only when they agree on a mild turn. One smooth sideways adjustment then reduces that foreshortening inside the verified face oval. It uses only pixels already inside the face and fades to zero before the edge of the oval, so hair, clothing, background, and the facial outline remain unchanged. It never generates the hidden side of a profile, and an already front-facing face stays exactly as photographed.
