The authors present work that was conducted as a collaboration between Cambridge University and MIT. The work is a continuation of previous research at Cambridge University, where several view-sequential 3D displays were built. The authors discuss a new display which they built and compare performance to previous versions. The new display utilizes a DMD(More)
Stereo vision is a resource-intensive process. Nevertheless, it has evolved in many animals including mammals, birds, amphibians and insects. It must therefore convey significant fitness benefits. It is often assumed that the main benefit is improved accuracy of depth judgments, but camouflage breaking may be as important, particularly in predatory animals.(More)
A common artefact of time-sequential stereoscopic video displays is the presence of some image ghosting or crosstalk between the two eye views. In general this happens because of imperfect shuttering of the Liquid Crystal Shutter (LCS) glasses used, and the afterglow of one image into another due to phosphor persistence. This paper describes a project that(More)
The Anaglyph 3D method of stereoscopic visualization is both cost effective and compatible with all full-color displays, however this method often suffers from poor 3D image quality due to poor color quality and ghosting (whereby each eye sees a small portion of the perspective image intended for the other eye). Ghosting, also known as crosstalk, limits the(More)
Anaglyphic 3D images are an easy way of displaying stereoscopic 3D images on a wide range of display types, eg. CRT, LCD, print, etc. While the anaglyphic 3D image method is cheap and accessible, its use requires a compromise in stereoscopic image quality. A common problem with anaglyphic 3D images is ghosting. Ghosting (or crosstalk) is the leaking of an(More)
— In 1853, William Rollman 1 developed the inexpensive and easy to use anaglyph method for displaying stereoscopic images. Although it can be used with nearly any type of full-color display, the anaglyph method compromises the accuracy of color reproduction, and it often suffers from cros-stalk (or ghosting) between the left-and right-eye image channels.(More)
A key problem in telepresence systems is how to effectively emulate the subjective experience of being there delivered by our visual system. A step toward visual realism can be achieved by using high-quality panoramic snapshots instead of computer-based models of the scene. Furthermore, a better immersive illusion can be created by enabling the free(More)
