Cataract surgery replaces the aged human lens with a transparent silicone implant. The new lens removes optical distortions and light scattering media, as well as a yellow filter. This talk describes the appearances of natural scenes before and after cataract surgery. While Color Constancy experiments showed small changes, color discrimination experiments had large changes. These results provide a mechanistic signature of Color Constancy and Discrimination.

  • 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.
