Fundamentals of Digital Imaging

The goal of this course is to provide a survey of the current state of the art in digital imaging. Day 1 will cover the basics of imaging and current products and capabilities. More in-depth information will be provided in days 2 and 3 and include the fundamentals of imaging and modeling, input and output devices in detail, characterization, calibration, and color management. Sessions will be limited to 20 participants. A copy of the textbook authored by the presenters will be included in the registration fee for Part II. Participants can register for Part I only, Part II only, or both Part I and Part II sessions. Morning and afternoon refreshment breaks and a box lunch will be provided.

Fees: Part I only - $295 per person, Part II only - $495 per person, Part I and II - $595 per person

Part 1 - Wednesday, July 11, 2012

Through a review of the technical basis of modern imaging hardware and software, participants will develop an understanding of the terminology used to describe modern imaging devices and processes, the formats used to store and display images, and the measures used to assess the quality of digital images. Participants will be able to evaluate the capabilities of image capture and display devices to record, represent, transfer and display images and information. Methods for the characterization and calibration of capture and display devices will be presented. With this understanding, you will be better able to choose equipment to satisfy the imaging needs for specific applications.

Part II - July 12 - 13, 2012

Part II builds upon the concepts learned in Part 1. After a brief review of the mathematics and basic radiometry, photometry and colorimetry, the applications of these principles to fundamental aspects of imaging, such as quantization, sampling and noise will be covered. This will allow the student to relate these concepts to bits per pixel, pixels per image and lines per inch, which are often used to characterize imaging devices. The student will learn the details of characterization and calibration of scanners, cameras, flat-panel displays and printers. Hands-on laboratories, using currently available instruments, will reinforce the in-class presentations. Participation in Part I is not required if students have already acquired the knowledge and skills related to concepts and principles presented in this day's sessions.
