Open Access Disparity Remapping Considering the Perception of Depth Structure

(PDF 10,806 kb)
A disparity remapping method that enlarges disparities inside objects is described. The method also reduces disparity gaps between objects and background. A disparity map is decomposed into a structure component and a high-frequency component, and two components are manipulated independently. Psychophysical experiments are conducted to evaluate the method. The task of participants in the experiments is to judge whether the object is convex or concave. The result of an experiment using random dot stereogram shows that if disparity gap between object and background exists, the detection threshold of depth structure increased. The result of another experiment using stereo pictures whose disparities are inverted inside objects shows that depth structure inside objects becomes more easily detected by the proposed method.

More about this publication?
  • 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.
