Using AI to calculate family resemblance

There are always those who say that their child looks more like their mother or their father. How about using math and Artificial Intelligence to be sure? The facial-matching application can answer you.

Implementation details

1.Get the image files for father, child and mother:

       father_file = request.files['father_image']
       child_file = request.files['child_image']
       mother_file = request.files['mother_image']

2. Use CV2 library to encode the images:         

       father_img = cv2.imdecode(np.frombuffer(father_file.read(), np.uint8), cv2.IMREAD_COLOR)
       child_img = cv2.imdecode(np.frombuffer(child_file.read(), np.uint8), cv2.IMREAD_COLOR)
       mother_img = cv2.imdecode(np.frombuffer(mother_file.read(), np.uint8), cv2.IMREAD_COLOR)

3. Compare father and child using Deepface verify:

       father_verification = DeepFace.verify(
           img1_path=child_img,
           img2_path=father_img,
           model_name="VGG-Face",
           detector_backend="retinaface",
           enforce_detection=True
       )

4. Compare mother and child using Deepface.verify:      

 mother_verification = DeepFace.verify(
           img1_path=child_img,
           img2_path=mother_img,
           model_name="VGG-Face",
           detector_backend="retinaface",
           enforce_detection=True
       )

5. Calculate similary percentages:       

father_similarity = 1 - father_verification['distance']
       mother_similarity = 1 - mother_verification['distance']
       return jsonify({
           "resemblance_to_father": father_similarity * 100,
           "resemblance_to_mother": mother_similarity * 100
       })
