Lightfield imaging focuses on capturing and processing discrete representations of the radiance in 3D space. Compared to conventional imaging (2D), lightfield imaging captures all rays individually, i.e. it captures the full 4D radiance. The goal is to multiplex the 4D radiance onto a conventional 2D sensor. To do that, lightfield imaging demands sophisticated optics implemented in plenoptic cameras and microscopes. Final 2D image generation is done computationally and is based on creating 2D projections of the 4D radiance. This course presents lightfield analysis in rigorous, yet accessible, terms. Mathematical foundations are used to demonstrate new computational methods for lightfield processing and image rendering, including digital refocusing, perspective viewing, superresolution, multispectral and HDR capture, and polarization imaging. While emphasizing theoretical understanding, it also explain approaches and engineering solutions to practical problems in computational imaging Benefits: Attendees will be able to: Learn the main principles of lightfield imaging, as it applies to photography, microscopy, and scientific imaging in general. Describe what lightfield imaging is and how it works; summarize the goals and benefits of this new method. Derive the main mathematical relations and be able to use them conceptually in research publications. Write basic lightfield rendering code and produce real refocusing/3d/multispectral results. Have a basic understanding of ideas and designs that allow one to design his/her own lightfield cameras or microscopes. Intended Audience: researchers and practitioners working in diverse fields of imaging including photography, color imaging/monitors, medical imaging, general microscopy, and others. Only basic algebra is required; a working knowledge of programming will help students write their own rendering algorithms after the course. Todor Georgiev is a principal engineer at Qualcomm, working on new imaging technologies. Having background in theoretical physics, he concentrates on applications of mathematical methods to image processing, optics, and computer vision. Georgiev holds more than 50 patents and has published numerous articles on imaging and lightfield technology.

The underlying cause of such a mismatch is the fact that different devices and media are capable of reproducing different ranges (gamuts) of colors, e.g., certain cyan colors are inaccessible on displays, certain reds cannot be captured using cameras, and some blues cannot be printed. In the face of such constraints, it is nonetheless necessary to do something about irreproducible colors. This is where color gamut mapping comes into play, by assigning reproducible colors to all original ones, in a controlled way and taking the color reproduction process aims into account. This short course, based on the instructor s Color Gamut Mapping book, provides an introduction to color reproduction, makes the role of gamut mapping explicit in its context, discusses how it is implemented in actual color management systems, and focuses on sketching out the variety of gamut mapping solutions proposed over the last thirty years. Participants can expect to gain an understanding of the factors that affect color reproduction when gamut differences are present and to 5

9 CIC22 and 2nd IADP Congress T5A: Normal and Defective Color Vision across the Lifespan 8:00 10:00 am (2 hours) Instructor: Caterina Ripamonti, Cambridge Research Systems Ltd. and UCL Institute of Ophthalmology The course provides a general introduction to normal and defective color vision and describes the principles of some existing software and tools that can be used to simulate how images may be perceived by observers with normal or defective color vision across the lifespan. The first part of the course provides the physiological fundamentals to understanding how color vision operates and focuses on the causes underlying differences in the perception of color. An analysis of the differences between color vision in normal trichromats and observers affected by inherited or acquired color deficiencies is given. Inherited color vision deficiencies include dichromacy, anomalous trichromacy, and monochromacy. Acquired color vision deficiencies include defects of the lens (i.e. cataracts) and other pathological changes in the retino-cerebral pathway (i.e. glaucoma). The differences between normal trichromats and affected observers are considered in terms of spatial, temporal, and color resolution as well as their light and dark adaptation processes. The second part of the course concentrates on simulating how vision changes during one s lifespan.

T1B: Color Calibration of Imaging Systems 10:15 am 12:15 pm (2 hours) Instructor: Phil Green, Gjøvik University College Calibration is an essential step in any color reproduction workflow, as it ensures that the color appearance of an object or scene can be communicated through the different devices in use within the workflow, from capture to preview and output. A variety of techniques are available to calibrate an imaging device, depending on the technology and the application. Frequently the goal is to make the device match a given reference condition (such as srgb for display or FOGRA39 for print), but in other cases it may be necessary to provide a transform between appearance (or colorimetry) and device signals in the form of an ICC profile. Calibration goals may include matching of white points, neutral scales, primaries and even complete characterization data sets. Benefits: Attendees will be able to: Understand and describe a range of calibration methods. Select a suitable calibration method 7

11 CIC22 and 2nd IADP Congress T3B: Measuring and Modeling Individual Differences in Color Matching Functions 10:15 am 12:15 pm (2 hours) Instructor: Mark Fairchild, Rochester Institute of Technology Observer metamerism refers to the fact that spectrally different stimuli might match in color for one observer (a metameric match), but mismatch significantly for some other color-normal observers. The fundamental cause of observer metamerism is that individual color matching functions differ due to natural anatomical and physiological variation in the visual system. Factors include lens and macula optical density, cone photopigment type, cone morphology, and photopigment density. Explored are causes of individual differences in color matching functions, the magnitude of mismatches that can result, methods for measuring individual responses, and mathematical models for predicting individual functions and the range of mismatches that can be expected across the population of color-normal observers for given stimulus properties. Benefits: Attendees will be able to: Explain the fundamental components of visual anatomy and physiology that define color matching functions. Describe the causes and potential magnitudes of variation in each of the component of color matching functions. Estimate how observer variability in color matches depends on the spectral properties on the stimuli. Compute the magnitude of potential observer mismatches for a given pair of stimuli. Describe two methods for quantifying potential observer metamerism: Categorical and Statistical. Infer the tradeoffs in stimulus (e.g. display) between competing functions such as maximizing gamut volume and minimizing observer differences. Intended audience: anyone using colorimetry to design or evaluate potentially metameric stimuli. This includes scientists and engineers in displays, cinema, photography, lighting, computer graphics, and materials.

Non-uniform illumination increases the range of light from a scene. Although HDR techniques are often associated with recording natural images, such as those by photographer Ansel Adams, they can be used to improve medical imaging, for example in endoscopy. After providing a detailed description of the dynamic range problem in image acquisition, this course focuses on standard methods of creating and manipulating HDR images, replacing myths with measurements of scenes, camera images, and visual appearances. The course presents measurements of the limits of accurate camera acquisition (range and color). It also shows measurements of the usable range of light from displays, considering human intraocular scatter. It discusses the principles of tone rendering, the role of HDR spatial comparison, and review HDR in medical imaging. 12

T1D: What Color is 3D? 3:45 5:45 pm (2 hours) Instructor: Matt Cowan, Entertainment Technology Canada, Ltd. Stereoscopic movies have a complex path from the point of action to the ultimate viewer s eyeball. Color is impacted both physically and perceptually at many steps. The traditional red-green glasses approach has an obvious impact on color, and fortunately those days are behind us. In production, beamsplitter rigs alter the color that is captured by each camera and attempts are made to correct this to a fully neutral state. In the theatre, several approaches are used to project 3D. Polarization adds minor color shifts and a newer technology, spectral division (Dolby s approach). offer color challenges. The introduction of laser based projection is offering new opportunities and challenges in image reproduction. Brighter 3D projection changes the appearance of color and dynamics, and the implementation of a 6P laser based spectral division will have some interesting observer metamerism effects. This course gives an overview of the basic production and projection techniques for cinema content, and address in detail how these affect the color that an audience sees. The course addresses the color and perception issues of taking a movie intended for the big screen, and repurposing it for the home television. The impact of narrow band laser primaries is also addressed. 13

Because of the way that color is processed in the human visual system, SPDs need not have power at every wavelength of the visible spectrum. With the fast pace of technological development, light sources can now be developed with SPDs vastly different than those historically used for illumination. Ways to measure, and even define, color rendering continues to be debated. This course explores SPD types, methods for predicting illuminated object color, color rendering metrics, and the relationship between SPD and luminous efficacy. Benefits: Attendees will be able to: Explain how human color vision pertains to color rendering. Understand the impact of light source SPD on luminous efficacy. Differentiate the SPDs of various lighting technologies. Evaluate different definitions of color quality and related metrics. Discuss the future of light source SPD and color rendering measurement.
