This course describes the context, structure, and applications of spatio-chromatic vision models for imaging. We begin with a brief review of the important characteristics of the visual system and the basic concepts of color science. We then develop a general framework for spatio-chromatic vision models that is based on trichromacy, color opponency, and the limited spatial frequency response of the vision system. Next we discuss applications of these models to color image quantization and digital color halftoning. During the second half of the course, we introduce a more complex group of models that account for the multi-channel nature of the visual system, the dependence of percept on contrast, and the role of the psychometric function in describing detection and discrimination. We then discuss potential applications of this model to image quality assessment.
Benefits:
Tutorial participants will be able to: - Understand the fundamental spatiochromatic aspects of the visual system, and how they can be captured in models
- Know how spatio-chromatic models for the human visual system can be used in the development of color image quantization and halftoning algorithms, and also for image quality assessment
Intended Audience:
This course is intended for scientists, engineers, analysts, and managers involved in the design, engineering, manufacturing, marketing, or evaluation of imaging products, algorithms, or systems. Participants should be familiar with the function and basic properties of color imaging systems.

Implementing and Using ICC v4 Color Management
Instructor: Ingeborg Tastl and Jack Holm, Hewlett-Packard
|
|
In 2002, the International Color Consortium (ICC) published ICC.1:2001-12, a specification for version 4 color profiles, and made it available over the web page (www.color.org). This specification addresses a number of ambiguities and interoperability issues that previously caused difficulties in the use of ICC color management. Colorimetric rendering intents are now required to be measurement based, and can be relied on for proofing or color re-rendering. A reference medium has been defined to enable cross-vendor interoperability with the perceptual intent. Finally, the new lutAtoBtype significantly extends color transform capability. Several companies support v4 profiles in applications, drivers and operating systems. More recently, software is becoming available to generate customized ICC v4 profiles. This course will discuss the major conceptual, implementation, and use differences between v2 and v4ICC, with the help of a set of concrete case studies. Furthermore, during the “hands-on” part of the tutorial, participants will generate a v4 ICC profile, and analyze and use it in a set of specific workflows.
Benefits:
This course will enable the attendee to: - Understand the differences between the ICC v2 and the new ICC v4 color management framework, and what to expect from color management moving forward
- Generate, analyze, and use v4 ICC profiles containing both colorimetric and perceptual rendering intents for input and output devices
- Select the most appropriate and robust color management workflows for particular groups of users (professional and consumer), and for particular tasks
- Make decisions based on advanced understanding of color management at a systems level
Intended Audience:
This course is intended for application developers, imaging workflow designers, system architects, color engineers and scientists and anyone in the professional imaging community (e.g. professional photographers, graphic designers) interested in the latest developments of ICC color management. Participants should be familiar with the basic principles of color management.

Color Image Processing for Image Capture
Instructor: Michael A. Kriss, Consultant
|
|
The course is designed to cover the basic technical issues governing the capture of color images by means of a color digital scanner or a color digital still camera. The course will start with the basic relationships between the effective spectral sensitivities of the capturing device (camera or scanner), the real life spectral reflectance and illuminants as well as the spectral reflectance (transmissions) of the colorants that form a hard copy image. In the case of a color digital scanner the impact of sampling (aliasing), single pass scans using multiple linear arrays, single pass scans using a linear array with a Color Filter Array and multiple pass scans using a single linear array with multiple light sources will be discussed. Optical versus digital resolution and the art of de-screening halftones will be covered as will the issue of color balance and adjustments for different input media. In the case of digital still cameras a brief survey of imaging sensor technology will be provided. The major emphasis will be on how single sensor imagers (with color filter arrays or with depth wise imaging sites) capture a color image and the digital processing required to reproduce full color images free of major artifacts and with good color reproduction. The topics covered will be sampling, aliasing, color filter arrays and advanced demosaicing of CFA images, white balance for different illuminants, color profiles, color gamut, noise reduction, and image enhancement. A special look at high dynamic imaging and processing will be presented.
Benefits:
This course will enable the attendee to: - Recognize the major issues around the capture of color images by digital systems

Color in Computer Graphics
Instructor: Gary Meyer, Univ. of Minnesota
|
|
This course will survey advances in computer graphics hardware and software that have led to important recent developments in the simulation of color appearance. The course will begin with a brief overview of the color calculation methods, color representation schemes, and color reproduction techniques that are commonly employed in computer graphics. A survey of important computer graphic applications involving color will also be provided. The course will then focus on four specific areas that have had a dramatic impact on color appearance simulation in computer graphics. The use of a digital camera as a data acquisition device to measure and record complex surface reflectance information will be described. Per-pixel shading hardware that facilitates real-time display and manipulation of this acquired reflectance data will be discussed. The application of digital video projectors to "paint" the surface of an object and simulate the appearance of a difference material will be presented. Finally, new computer graphic surface reflection models that are used to render complicated reflectance phenomena, such as skin and hair, will be overviewed.
Benefits:
This course will enable the attendee to: - Define potential areas of overlap between the fields of computer graphics and color science
- Describe recent developments in computer graphic hardware and software
- Explain how the field of computer graphics approaches the measurement and modeling of color appearance
- Specify how certain recent computer generated motion picture special effects were accomplished
Intended Audience:
This course is intended for engineers, developers, and researchers in the color imaging and color appearance industries. An understanding of traditional color appearance measurement and modeling techniques will be assumed. Some familiarity with elementary PC graphics hardware and software would be helpful. An extensive background in computer graphics will not be required.

Digital cinema is here. Several movies have been captured entirely in the 1080 p24 digital format, without using any film. In post-production, digital intermediates are now used routinely to store entire movies digitally, even if some portions are 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 about 150 commercial cinemas worldwide that are now equipped with digital cinema projectors. Digital movie making presents an important and challenging application of color science and color management. The high contrast ratio and wide gamut of cinema film set goals for image coding and color management that are well beyond the limits of graphics arts. This course details the application of color science to digital cinema. We detail the technologies of D-cinema, from camera and scanner technology, through processing, to digital cinema display equipment and film recorders. We explain the application of color science to each of these steps.
Benefits:
This course will enable the attendee to: - Evaluate the contrast ratio and gamut constraints of various image coding systems
- Understand color image coding for HDTV and digital cinema
- Understand the color signal processing required to process cinema-class imagery
Intended Audience:
This course is intended for scientists, engineers, and managers involved in the design, engineering, and evaluation of digital cinema, and more generally, high-quality continuous-tone imaging products, algorithms, or systems. Participants should be familiar with color science and color image coding, and should have no fear of mathematics.

Making movies involves more than science, and reproducing color in movies involves more than color science. The preceding course, T5A/B, Color Science for Digital Cinema describes how color science is being applied to digital cinema; however, a great deal of tradition, craft, and art remains. In processing color images for digital cinema exhibition, and in processing images for film recording of digital masters, many color issues cannot yet be reduced to hard science. However, the emerging science of color appearance modeling promises to make a contribution. In this course, three masters of digital cinema exhibition describe how they have worked to introduce color science, and elements of color appearance models, to the workflow of digital cinema mastering and release. Brad Walker will explain some color appearance aspects of the signal processing within Texas Instruments’ DLP Cinema projector. Joseph Goldstone, formerly with ILM, will explain some nuances of the film-out process, including issues in measurement. Josh Pines of Technicolor will describe the system that he has developed to enable the previewing, on a digital cinema projector, of images that will result from projection of a film recording.
Benefits:
This course will enable the attendee to: - Understand color as represented in film images
- Explain how color appearance phenomena are accommodated in digital cinema
- Recognize the challenges of color measurement in a high contrast ratio, wide-gamut environment
Intended Audience:
This course is intended for scientists, engineers, and managers involved in the design, engineering, and evaluation of digital cinema, and more generally, high-quality continuous-tone color imaging products, algorithms, or systems. Participants should be familiar with color science and color image coding, and should have no fear of mathematics.
