I am using deep face library in order to get several faces in one picture, DeepFace.detectFace(), only detect one face, but if I use the backends separately without use DeepFace I can extract all faces, is it possible to use DeepFace.detectFace() in order to get all faces in one photo?
Thanks
I just found this question so adding my 2 cents here.
The deepFace has 2 face detection methods: detect_face(), detect_faces(). I tried both of them on the input image which had 2 faces. The detect_face() method returned 2 faces while the detect_faces() returned only 1.
I also explored the retinaFace library. The RetinaFace.detect_faces(input_img) works better than the above 2. It will return a dictionary containing more details like the position of the detected faces, conf-score, facial area, landmarks, etc.
detector = FaceDetector.build_model('opencv')
faces_1 = FaceDetector.detect_face(detector, 'opencv', img1)
faces_2 = FaceDetector.detect_faces(detector, 'opencv', img1)
faces_3 = RetinaFace.detect_faces(img1)
print(len(faces_1))
print(len(faces_2))
print(len(faces_3))
print(faces_3)
Output:
2
