Summary
In this chapter, we discussed Haar cascades and integral images. We learned how the face detection pipeline is built. We learned how to detect and track faces in a live video stream. We discussed how to use the face detection framework to detect various face parts, such as eyes, ears, nose, and mouth. We also learned how to overlay masks on top on the input image using the results of the face parts detection.
In the next chapter, we will learn about video surveillance, background removal, and morphological image processing.
