Face Analysis API offers three types of face image processing, leveraging advanced deep learning technology designed for the automation of processes related to face analysis in pictures: - Detection. It detects human faces in images, provides the coordinates of the detected face's location, and offers a 'confidence' score reflecting the accuracy of the detection. - Key points. Our Face Analysis API automatically identifies five key points on a human face, including the left and right eyes, nose, and the corners of both lips. - Comparison. Optionally, the algorithm returns an embedding for each detected face. Utilizing these features, it can accurately determine whether different faces belong to the same person.
