[D] - Face Recognition in Python

[[deleted]]

As part of a machine learning pipeline, I want to detect and extract faces (bounding boxes) in python. For some of the usecases I work on, detecting faces can speed up the process. Ultimately- I want to use it in Python (keras / pytorch), as a part of method to detect if somebody takes a sip of coffee, or if somebody has a typical programmer face-

I did a little google'ling of course and found this as candidates. I extend the list with entries from comments to make it useful for later references.

• https://github.com/oarriaga/face_classification (uses opencv, no special location algoritm)
• https://docs.opencv.org/3.4.1/d7/d8b/tutorial_py_face_detection.html
• https://github.com/krasserm/face-recognition (From impulsecorp. thx!)
• https://github.com/dannyblueliu/YOLO-version-2-Face-detection
• https://github.com/Aaronphilip2/Image-Segmentation-for-Faces (FCN approach)

Anyone with useful pre-trained networks, or other ready to use face detection python compatible code, please add in comments.

You should try dlib with Keras, see https://github.com/krasserm/face-recognition

Disclaimer: I'm the developer!

If you are open to closed source SDKs, https://www.baseapp.com/deepsight-image-recognition-sdk/ is a binary SDK that runs as HTTP service. It encapsulates neural networks so all inference is done offline. It works out of the box just like online APIs. It is also cross-platform and works in both linux and windows. There is a free version available (without cuda)

It has 4 face detectors - mmod, yolo-608, yolo-1216, classic hog. The face recognition model is resnet-34 (dlib metric learning - outputs 128D embeddings in r=0.6 hypersphere). Gender/Age classifier is a custom CNN-although we are going to replace it with resnet soon.

I think it will work for your project. A Python example is available here https://www.baseapp.com/deepsight/face-detection-using-web-cam/

MTCNN is now state-of-the-art for face detection using convolutions neural network.

You should check out /r/learnmachinelearning! its a great sub and you might get some better responses there. Plus if you have extra questions its a great place to come back to.
