If marketing folks want to breathe new life into an existing technology, the
method du jour is to tack “digital” onto the name. Today we have digital
cable, digital cell phones, digital fuel injection, and now, digital video. But
unlike some other technologies that have recently earned the digital prefix,
digital video isn’t just a minor improvement over the old way of doing things.
Digital video is a revolution that is changing the way we think about and use
The Handbook of Image and Video Processing contains a comprehensive and highly accessible presentation of all essential mathematics, techniques, and algorithms for every type of image and video processing used by scientists and engineers. The timely volume will provide both the novice and the seasoned practitioner with the necessary information and skills to be able to develop algorithms and applications for multimedia, digital imaging, digital video, telecommunications, and World Wide Web industries.
Visual quality assessment is an interdisciplinary topic that links image/video processing, psychology and physiology. Many engineers are familiar with the image/video processing; transmission networks side of things but not with the perceptual aspects pertaining to quality. Digital Video Quality first introduces the concepts of human vision and visual quality. Based on these, specific video quality metrics are developed and their design is presented. These metrics are then evaluated and used in a number of applications, including image/video compression, transmission and watermarking.
Growth naturally stimulates change, and CCTV technology has
been no exception. A system that once merely required cameras,
cabling, and video monitors has now become a complex electronic
confi guration of equipment intertwined with both computer and
telecommunications technologies. This dramatic change is directly
related to the introduction of digital technology. Why do we need
to understand how digital technology works, and what does it
have to do with the future of security? It’s simple—the newest
revolution in technology is pervasive computing.

Signals represent information about data, voice, audio, image, video… There are many ways to
classify signals but here we categorize signals as either analog (continuous-time) or digital (discretetime).
Signal processing is to use circuits and systems (hardware and software) to act on input signal
to give output signal which differs from the input, the way we would like to.
This book provides a full and comprehensive coverage of video and television technology including the latest developments in display equipment, HDTV and DVD. Starting with TV fundamentals, the bulk of the book covers the many new technologies that are bringing growth to the TV and video market, such as plasma and LCD, DLP (digital light processing), DVD, Blu ray technology, Digital television, High Definition television (HDTV) and video projection systems.
Digital filters are widely used in processing digital signals of many diverse applications, including
speech processing and data communications, image and video processing, sonar, radar, seismic and
oil exploration, and consumer electronics.
Since the digital representation of raw video signals requires a high capacity, low complexity video coding algorithms must be deﬁned to eﬃciently compress video sequences for storage and transmission purposes. The proper selection of a video coding algorithm in multimedia applications is an important factor that normally depends on the bandwidth availability and the minimum quality required.
Digital television is being widely adopted for various applications ranging from high-end applications,
such as studio recording, to consumer applications, such as digital cable TV and digital DBS
(Direct Broadcasting Satellite) TV. For example, several digital video tape recording standards, using
component format (D1 and D5),
