Tutorial Program
The goal of the tutorial program is two-fold:
- to offer a basic education in color imaging for those new to the field;
- to keep attendees abreast of the latest developments and applications.
To serve the first goal, we plan to offer a 2-day course taught by the renowned Dr. Robert Hunt, providing an extensive overview of basic color science and imaging. This course has been tremendously successfuly at past CIC meetings. To serve the second objective, a variety of advanced tutorials will be offered in the areas of color vision, appearance, image quality, color imaging technologies, applications, and systems. Details will be forthcoming.
Fees will include a discount for IS&T and SID members, and a substantial discount for students. If you would like more information about the tutorials, or would like to suggest a topic of interest to you, please contact the tutorial chairs: Joann Taylor (joannt@telephort.com) and Gaurav Sharma (gsharma@ece.rochester.edu).

T3B — 2 hour tutorial Tuesday November 8, 2005 , 10:20 am to 12:20 pm T3B–Device Simulation for Image Quality Evaluation Instructor: Joyce Farrell, Stanford University | ||||||||||||||||||
|
This course uses the Image Systems Evaluation Toolbox (ISET) to simulate and evaluate the influence that different imaging system components have upon perceived image quality. The course is organized into sections corresponding to the six ISET modules that simulate visual scenes, optics, sensors, image processing, displays, and human observers. The scene module uses high-dynamic multispectral image data to calculate the spectral radiance (photons/ sec/nm/sr/m2) at each point in a sampled scene. The optics module converts the scene radiance data to an irradiance image at the sensor. The sensor module converts the sensor irradiance image into electron counts within each pixel of the image sensor. The processor module transforms the electron count into a digital image and applies both demosaicing and color balancing algorithms. The display module applies rendering algorithms and calculates the spectral radiance generated by the final displayed image. Finally, ISET includes several image quality metrics (e.g., CIELAB, S-CIELAB) that measure the perceptual difference between any two radiance images. When one of the radiance images corresponds to the original scene data, the image quality metrics provide a measure of image fidelity. This course will include many practical examples that illustrate how to use ISET through graphical user interface and scripting. Examples will include methods for visualizing and quantifying different imaging system components that influence perceived image quality.
Benefits:
Intended Audience: Intended for engineers, scientists, students, and managers who wish to understand how changes in imaging system components will affect perceived image quality, the course will be especially useful for engineers who are designing optics, sensors, processing algorithms, or displays for digital cameras and cell phone imagers.

T4A — 2 hour tutorial Tuesday November 8, 2005 , 8:00 to 10:00 am T4A–Color Science for HDTV and Digital Cinema Instructor: Charles Poynton, Consultant | ||||||||||||||||||
|
High-definition television (HDTV) broadcasting is now commonplace and most television productions are being made in HDTV (even if “downconverted” to standard-definition television, SDTV, for analog broadcast). Digital cinema is also now in the mainstream. Several movies have been captured entirely in the 1080p24 digital format (derived from HDTV) without the use of any film. In post-production, digital intermediates are now used routinely to store entire movies digitally, even those portions scanned-in from film. Digitally-produced movies are “filmed-out” (recorded to 35 mm motion picture film) for exhibition, but digital masters are made for exhibition in the approximately 150 commercial cinemas worldwide now equipped with digital cinema projectors. Digital HDTV production and digital movie making present important and challenging applications of color science, color image coding, and color management. The high contrast ratio and wide gamut of cinema film set goals well beyond the limits of graphics arts. This tutorial details the application of color science to HDTV and digital cinema. It explores the technologies of HDTV and D cinema, from camera and scanner technology, through processing, to digital cinema display equipment and film recorders. The application of color science to each of these steps is explained and how color appearance models are finding new applications in this domain are explored.
