Face Recognition! [iPhone]

Detect human faces and compare similar ones, organize people into groups according to visual similarity, and identify previously tagged people in images.
You can upload a photo with any amount of faces on it, the app will find all faces marked, together with an age estimation of each person and all relative marks on the face. Our face detector seems to be highly accurate.
Find look-alike celebrities on the web using the face recognition. Results can vary on the resolution or quality of the photo. For the best result, please upload a photo of a frontal face. Result is displayed for each face detected.
Detect one or more human faces in an image and get back face rectangles for where in the image the faces are, along with face attributes which contain machine learning-based predictions of facial features. After detecting faces, the app will show you the age, gender, and the celebrity look alike of the face uploaded.

Check the likelihood that two faces belong to the same person. The App returns a confidence score about how likely it is that the two faces belong to one person.
For providing more accurate results, please use images which contain only a single face.
