Chapter 8. Image processing
The previous chapter covered one-dimensional audio signals. But IoT devices often process and analyze higher dimensional signals, in particular, two- or three-dimensional images. Embedded devices can acquire data from various cameras, including widely available USB web cams and more advanced cameras, e.g. infrared (thermal) cameras. Images are subsequently analyzed to control a specific process. An IoT device can monitor manufacturing by identifying damages in the component fabrication. A small camera mounted in your car can recognize traffic signs. An artificial intelligence (AI) module can use this information, along with data coming from sensors monitoring vehicle speed, to autonomously steer the car. IoT devices ...
