Multidimensional Structure of Colorfulness: Chroma Variation in Color Images of Natural Scenes

In a previous investigation it was found that the perceptual quality of images of natural scenes depended upon their subjective colorfulness when the images were transformed by varying of chroma.1 The transformations were performed over the color point distributions in the CIELUV perceptually uniform color space where each color point represented one pixel of a corresponding image. The experiments with uni-dimensional scaling of colorfulness have shown that the colorfulness can be represented as a linear combination of average chroma and variability of chroma. However, such a representation held only within each scene: there was no regular rule to compare different scenes even with significantly different average chroma of the original images. The results of multidimensional scaling of colorfulness reveal the multidimensional structure of this attribute. Possible interpretations of subjective dimensions are discussed.

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.
