  • About the Edition

    The process by which an image is formed, processed, and displayed can be conceptualized as a chain of physical events called the imaging chain. By mathematically modeling the imaging chain, we can gain insight into the relationship between the camera design parameters and the resulting image quality. The mathematical models can also be used to optimize and assess the design of a camera for specific applications before expenditures are committed to building hardware. Modeling the Imaging Chain of Digital Cameras teaches the key elements of the end-to-end imaging chain for digital camera systems and describes how elements of the imaging chain are mathematically modeled using the basics of linear systems mathematics and Fourier transforms. The emphasis is on general digital cameras designed to image incoherent light in the visible imaging spectrum. The reader will learn how digital camera design parameters are related to the elements of the imaging chain and how they influence the resulting image quality. The book also discusses the use of imaging chain models to simulate images from different digital camera designs for image quality evaluations.

    The transformation of digital camera raw sensor image data into a full-color fully processed image involves a complex chain of computations. The possible orderings of individual operations and associated implementation details that constitute the image processing chain can lead to a .   Most books on digital imaging have followed the traditional imaging chain of input-manipulation-output. The Complete Guide to Digital Imaging argues that the digital designer will achieve better results by following the reverse sequence: output-manipulation-input. If artists know the final usage, they’ll be spared the aggravation of scanning a photo at ultra-high resolution when all Reviews: 1.

    Digital imaging is a process of creating digital images such as printed texts, photographs or networks through the use of image machine, manuscripts, artwork or digital camera. In other words, digital imaging is a method by which the content of a file or document is digitized and converted into a readable digital format from an analog format. Gain a greater understanding of optical gas imaging (OGI) technology and how it can help you find and repair gas leaks quickly, saving time, money, and the environment. This iBook for iOS and MacOS offers: In-depth look at industry applications. Rich video content. Details on how OGI and infrared work. Expert tips for maximizing OGI surveys.

The emphasis is on general digital cameras designed to image. Modeling the Imaging Chain of Digital Cameras is derived from a course that I teach to share my perspectives on this topic. This book is written as a tutorial, so many details are left out and assumptions made in order to generalize some of the more difficult concepts.

[Robert D Fiete; SPIE (Society)] -- The process by which an image is formed, processed, and displayed can be conceptualized as a chain of physical events called the imaging chain. By mathematically modeling the imaging chain, we can.

So far, this book has focused on the part of the imaging chain that forms the image created by the digital camera as well as the processing to enhance that information. The next step of the imaging chain is the display of the image in a manner that allows the users to visualize and interpret the information (Fig.

The principal links of the imaging chain are the radiometry, the camera, the processing, the display, and the interpretation of the image (Fig. The imaging chain begins with the radiometry of the electromagnetic energy that will create the image.

This energy may originate from the sun, a.

It is important at this point to look at the combined effect of the optics and sensor on the image quality produced by the camera (Fig. We have shown that the optics and the digital sensor each impose a fundamental limit on the detail that can be imaged with a digital camera.

The links in this chain impose physical limitations that prevent the camera from capturing a "perfect" image, i.e., an image that is an exact copy of the scene information.

For example, a digital image will not continue to display higher details in the scene as we view the image under higher and higher magnification (Fig. Modeling the imaging chain has become a critical design tool to understand the relationship between design trades and image quality in camera systems.

The mathematical models for the fundamental components of an imaging chain are well understood and have been validated using working camera. Modeling the imaging chain of digital cameras is necessary to relate the camera design parameters to the resulting image quality. Applications include designing cameras to meet image quality requirements as well as identifying fake images.

Digital imaging or digital image acquisition is the creation of a digitally encoded representation of the visual characteristics of an object, such as a physical scene or the interior structure of an object.

The term is often assumed to imply or include the processing, compression, storage, printing, and display of such images.A key advantage of a digital image, versus an analog image such as.
