Paired comparison experiments are frequently used to gather observer preference data in many areas of image enhancement. However, due to the large quantity of comparisons each individual must complete, these experiments are typically carried out with few observers. Taking this method onto the web is a quick way of gaining a larger number of observers and preference judgements. This work examines the validity of web based paired comparisons and whether the loss of control over viewing conditions causes significantly different results.

  • 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, and a vibrant interactive papers session. An endearing symbol of the meeting is the Cactus Award, given each year to the author(s) of the best interactive paper presentation.
