In this paper, we discuss the use of computer graphics techniques to model and explain the structures commonly observed in color histograms of images. This includes an accurate simulation of the physical reflection and transport behavior of light energy within 3D environments, the precise modeling of an image capturing system, and an interactive visualization module to display color histograms. Based on the fundamental rendering equation that describes light reflection and transport in the 3D world, we classify the color histogram structures of color images, and relate them to various physical components in image formation, including scene illumination, material reflectance properties, and the surface geometry of objects. We further show how these histogram structures can be effected by the artifacts caused by the limitation of image capturing systems. Our results demonstrate that the use of accurate simulation procedures under a precisely controlled computer graphic environment can clearly illustrate the causes of the structures observed, and can provide unique insights and explanations of image formation.

More about this publication?
  • CIC is the premier annual technical gathering for scientists, technologists, and engineers working in the areas of color science and systems, and their application to color imaging. Participants represent disciplines ranging from psychophysics, optical physics, image processing, color science to graphic arts, systems engineering, and hardware and software development. While a broad mix of professional interests is the hallmark of these conferences, the focus is color. CICs traditionally offer two days of short courses followed by three days of technical sessions that include three keynotes, an evening lecture, a vibrant interactive (poster) papers session, and workshops. An endearing symbol of the meeting is the Cactus Award, given each year to the author(s) of the best interactive paper; there are also Best Paper and Best Student Paper awards.
