Video inspection systems are used in many commercial and industrial processes. Cameras—which range from those in inexpensive, low-definition black-and-white closed-circuit television (CCTV) systems to those in state-of-the-art high-definition digital-video systems—are used in diverse applications ranging from product inspection to traffic monitoring to real-time face recognition.
This article shows a few examples of how extracting useful data can minimize processing, memory size, and DSP usage—and illustrates how special features of Analog Devices video decoders2 can simplify video algorithms and speed up development of video inspection systems.
