Further reading

Visual processing is a deep topic, so this is only a small selection of places where you can read more about using a camera for visual processing:

• The Official Raspberry Pi Camera Guide at https://magpi.raspberrypi.org/books/camera-guide is an excellent resource for getting to know the camera, with many practical projects for it.
• To delve in far greater depth into using the Raspberry Pi Camera, I recommend the PiCamera documentation, available at https://picamera.readthedocs.io/.
• To gain insight into further techniques, the PyImageSearch website, at https://www.pyimagesearch.com, has great resources.
• OpenCV and visual processing is a complex topic, only briefly covered here. I recommend OpenCV 3 Computer Vision with Python Cookbook, by Alexey Spizhevoy and Aleksandr Rybnikov, from Packt Publishing, available at https://www.packtpub.com/application-development/opencv-3-computer-vision-python-cookbook, for more information.
