Over the years, there have been many studies conducted for whiteboard image detection, extraction and quality enhancements. However, the image quality attributes of the streaming whiteboard contents as well as users’ expectations from such whiteboard scenes are not well investigated.
Therefore, the primary goal of this work is to examine the effects of the different whiteboard image features on the overall quality of the whiteboard images. Particularly, the naturalness and legibility quality attributes of the images were investigated through psychovisual experiments. Our
experimental results show that increasing color attributes such as saturation, brightness and luminance contrast, lead to more legible whiteboard contents; which in turn increases the whiteboard image quality. Enhancement processes of the whiteboard backgrounds, however, show strong effects
on the naturalness attribute. But, when the general image quality is considered, observers tend to prefer more legible whiteboard image contents rather than the naturalness of the appearance.

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.
