Mastering Computer Vision with TensorFlow 2.x

Preparing the dataset for key-point detection

In this section, you will learn how to create your own data. This involves writing code and executing it so that the webcam in your PC lights up. Move your face to different positions and orientations and hit the spacebar and it will save an image of your face after cropping everything else out from the image. The key steps for this process are as follows:

1. First, we begin by specifying the path to the Haar cascade classifier. This should be located in your OpenCV/haarcascades directory. There will be many .xml files located there, so include the path for frontalface_default.xml:

face_cascade = cv2.CascadeClassifier('path tohaarcascade_frontalface_default.xml')

2. Next, we will define the webcam ...
