This textbook deals with the analysis and design of imaging systems and image processing systems. It contains in a single volume the background material necessary for understanding both the physics of such systems and the way in which the designs accomodate the visual perception of the observer. Of central importance is the mathematics of converting optical images to electrical signals and vice versa, whereby it is stressed that the quality of such conversions must be judged subjectively. The material is easily accessible to senior undergraduates and first year students. A knowledge of elementary physics, calculus, and linear systems theory is assumed, but an extensive mathematical and statistical background is not required. This third edition has been updated and includes chapters on color and the design of improved television systems, and an appendix describing the current status of high-defintion television throughout the world.
Klappentext zu „Fundamentals of Electronic Imaging Systems “
Image processing is a fascinating applications area, not a fundamental science of sufficient generality to warrant studying it for its own sake. In this area, there are many opportunities to apply art and experience, as well as knowledge from a number of sciences and engineering disciplines, to the creation of products and processes for which society has an expressed need. Without this need, work in the field would be sterile, but with it, image processing can readily provide the interested scientist or engineer with a professioilal lifetime of challenging problems and corresponding rewards. This point of view motivates this book and has influenced the selection and treatment of topics. I have not attempted to 1 be encyclopedic; this service has already been performed by others. It will be noted that the word "digital" is not in the title of this book. While much of present-day image processing is implemented digitally, this work is not intended for those who think of image processing as a branch of digital signal processing, except, perhaps, to try to change their minds. Image gathering and image display, vital parts of the field with strong effects on image quality, are inherently analog, as are all of the channels and media now used, or likely to be used in the future, to record TV signals and to transmit them to the home.
