Mastering OpenCV 4 with Python

Complete examples using the OpenCV DNN face detector

Next, we will see how to modify the face_detection_opencv_dnn.py script (from Chapter 11, Face Detection, Tracking, and Recognition) in order to do the following:

• Compute the output when several images (with possible different sizes) are fed to the network – the face_detection_opencv_cnn_images.py script
• Compute the output when several images (with possible different sizes) are fed to the network when the crop=True parameter in the cv2.dnn.blobFromImages() function—the face_detection_opencv_cnn_images_crop.py script

The output of the face_detection_opencv_cnn_images.py script is shown in the following screenshot:

The output of the face_detection_opencv_cnn_images_crop.py script is shown ...
