A collection of deep learning frameworks ported to Keras for face detection, face segmentation, face parsing, iris detection, and face verification.
This repository contains deep learning frameworks that we collected and ported to Keras. We wrapped those models into separate modules that aim to provide their functionality to users within 3 lines of code.
- Face detection:
- S3FD model ported from 1adrianb/face-alignment.
- MTCNN model ported from davidsandberg/facenet.
- Face landmarks detection:
- 2DFAN-4, 2DFAN-2, and 2DFAN-1 models ported from 1adrianb/face-alignment.
- Face parsing:
- BiSeNet model ported from zllrunning/face-parsing.PyTorch.
- Eye region landmarks detection:
- ELG model is ported from swook/GazeML.
- Face verification:
- InceptionResNetV1 model (model name: 20180402-114759) ported from davidsandberg/facenet.
- LResNet100E-IR model ported from deepinsight/insightface.
- IR50 model ported from ZhaoJ9014/face.evoLVe.PyTorch.
- Gender and age estimation:
- MobileNet model ported from deepinsight/insightface.
*Each module follows the license of their source repo. Notice that some models were trained on dataset with non-commercial license.
pip install keras==2.2.4 before initializaing models.)
This colab demo requires a GPU instance. It demonstrates all face analysis functionalities above.
models.detector.face_detector.FaceAlignmentDetector(fd_weights_path=..., lmd_weights_path=..., fd_type="s3fd")Arguments
fd_weights_path: A string. Path to weights file of the face detector model.lmd_weights_path: A string. Path to weights file of the landmarks detector model.fd_type: A string. Face detector backbone model of eithers3fdormtcnn.
Example
from models.detector import face_detector
im = cv2.imread(PATH_TO_IMAGE)[..., ::-1]
fd = face_detector.FaceAlignmentDetector()
bboxes = fd.detect_face(im, with_landmarks=False)The default model is 2DFAN-4. Lite models of 2DFAN-1 and 2DFAN-2 are also provided.

Example
from models.detector import face_detector
im = cv2.imread(PATH_TO_IMAGE)[..., ::-1]
fd = face_detector.FaceAlignmentDetector()
bboxes, landmarks = fd.detect_face(im, with_landmarks=True)models.parser.face_parser.FaceParser(path_bisenet_weights=...)Arguments
path_bisenet_weights: A string. Path to weights file of the model.
Example
from models.parser import face_parser
im = cv2.imread(PATH_TO_IMAGE)[..., ::-1]
fp = face_parser.FaceParser()
# fp.set_detector(fd) # fd = face_detector.FaceAlignmentDetector()
parsing_map = fp.parse_face(im, bounding_box=None, with_detection=False)models.detector.iris_detector.IrisDetector()Faster face detection using MTCNN can be found in this repo.
Example
from models.detector import iris_detector
im = cv2.imread(PATH_TO_IMAGE)[..., ::-1]
idet = iris_detector.IrisDetector()
idet.set_detector(fd) # fd = face_detector.FaceAlignmentDetector()
eye_landmarks = idet.detect_iris(im)models.verifier.face_verifier.FaceVerifier(extractor="facenet", classes=512)Argument
extractor: A string, one offacenet,insightface,ir50_ms1m, orir50_asia.classes: An integer. Dimension of output embeddings.
Example
from models.verifier import face_verifier
im1 = cv2.imread(PATH_TO_IMAGE1)[..., ::-1]
im2 = cv2.imread(PATH_TO_IMAGE2)[..., ::-1]
fv = face_verifier.FaceVerifier(extractor="facenet")
# fv.set_detector(fd) # fd = face_detector.FaceAlignmentDetector()
result, distance = fv.verify(im1, im2, threshold=0.5, with_detection=False, with_alignment=False, return_distance=True)models.estimator.gender_age_estimator.GenderAgeEstimator(model_type="insightface")Arguments
model_type: A string, onlyinsightfaceis supported now.
Example
from models.estimator import gender_age_estimator
im = cv2.imread(PATH_TO_IMAGE)[..., ::-1]
gae = gender_age_estimator.GenderAgeEstimator()
gae.set_detector(fd) # fd = face_detector.FaceAlignmentDetector()
gender, age = gae.predict_gender_age(im, with_detection=True)- insightface model, this file should be put in
./models/verifier/insightface/. - IR50-MS-Celeb-1M model, this file should be put in
./models/verifier/face_evoLVe_ir50/. - IR50-Asia-face model, this file should be put in
./models/verifier/face_evoLVe_ir50/.
It works fine on Colab at this point (2019/06/11) but for certain Keras/TensorFlow version, it throws errors loading 2DFAN-1_keras.h5 or 2DFAN-2_keras.h5.
- Keras 2.2.4
- TensorFlow 1.12.0 or 1.13.1
We learnt a lot from 1adrianb/face-alignment, zllrunning/face-parsing.PyTorch, swook/GazeML, deepinsight/insightface, davidsandberg/facenet, and ZhaoJ9014/face.evoLVe.PyTorch.
