Mtcnn face detection

MTCNN Two tasks can be achieved —— Face detection and face key point detection .

MTCNN It's integrated into python Library .

install

Be careful ： The following dependencies need to be confirmed before installation ：

python >= 3.4
opencv >= 4.1
Keras>=2.0.0

pip install mtcnn

Face detection

from mtcnn import MTCNN
import cv2
img=cv2.imread("../datas/face/ldh2.jpg")
img = cv2.cvtColor(img, cv2.COLOR_BGR2RGB)
detector = MTCNN()
face =detector.detect_faces(img)
print(face)
