In this chapter, we learnt how to access the webcam. We discussed how to take the keyboard and mouse inputs during live video stream. We used this knowledge to create an interactive application. We discussed the median and bilateral filters, and talked about the advantages of the bilateral filter over the Gaussian filter. We used all these principles to convert the input image into a sketch-like image, and then cartoonized it.
In the next chapter, we will learn how to detect different body parts in static images as well as in live videos.
