Chapter 5. Video Processing

Video processing has become one of the main applications of signal processing technology. One reason for the increasing importance of digital video is that it is everywhere, from YouTube to unpiloted military drones. The other reason is that digital video is hard to do—the algorithms are complicated, and they demand huge computational power. Thus, video applications will keep many of us employed for years to come!In this chapter, Keith Jack gives an in-depth treatment of digital video processing. The main topics include display enhancement, video mixing and graphics overlay, frame rate conversion, interlacing/deinterlacing, video scaling, and user controls (brightness, contrast, etc).You may have noticed that this ...
