Mastering OpenCV 4 with Python

Face detection with cvlib

For the sake of completeness, we are introducing the cvlib package in this section because it also provides an algorithm for face detection. This library is a simple, high-level and easy-to-use open source computer vision library for Python (https://github.com/arunponnusamy/cvlib). In order to detect faces with cvlib, you can use the detect_face() function, which will return the bounding boxes and corresponding confidences for all detected faces:

import cvlib as cvfaces, confidences = cv.detect_face(image)

Under the hood, this function is using the OpenCV DNN face detector with pre-trained Caffe models (https://github.com/arunponnusamy/cvlib/blob/master/cvlib/face_detection.py).
