Accurately describing the gamut of a color device is the basis for gamut mapping, device color characterization and device gamut volume prediction. There are many ways to describe gamut boundary in the past and the methods can be used in combination with each other for the more accurate and effective gamut boundary description. However, it is difficult to find a commonly used method after introducing the way of color space segmentation. In this paper, we reorganize the existing gamut boundary description techniques according to purpose and method. We also propose a new simple approach of predicting gamut boundary. This new approach uses a machine learning based Radial Basis Function Network(RBFN) that can simplify the gamut boundary description process. This simple method can directly predict the desired gamut boundary description.

  • For more than 30 years, the Electronic Imaging Symposium has been serving those in the broad community - from academia and industry - who work on imaging science and digital technologies. The breadth of the Symposium covers the entire imaging science ecosystem, from capture (sensors, camera) through image processing (image quality, color and appearance) to how we and our surrogate machines see and interpret images. Applications covered include augmented reality, autonomous vehicles, machine vision, data analysis, digital and mobile photography, security, virtual reality, and human vision. IS&T began sole sponsorship of the meeting in 2016. All papers presented at EIs 20+ conferences are open access.

    Please note: For purposes of its Digital Library content, IS&T defines Open Access as papers that will be downloadable in their entirety for free in perpetuity. Copyright restrictions on papers vary; see individual paper for details.
