Virtual characters are much in demand for animated movies, games, and other applications. Rapid advances in performance capture and advanced rendering techniques have allowed the movie industry in particular to create characters that appear very...
We consume video content in a multitude of ways, including in movie theaters, on television, on DVDs and Blu-rays, online, on smart phones, and on portable media players. For quality control purposes, it is important to have a uniform viewing...
Pointing in pictorial space: Quantifying the perceived relative depth structure in mono and stereo images of natural scenes
Maarten W.A. Wijntjes, Sylvia C. Pont
Article No.: 24
Although there has recently been a large increase in commercial 3D applications, relatively little is known about the quantitative perceptual improvement from binocular disparity. In this study we developed a method to measure the perceived...
Analysis of disparity distortions in omnistereoscopic displays
Vincent Couture, Michael S. Langer, Sébastien Roy
Article No.: 25
An omnistereoscopic image is a pair of panoramic images that enables stereoscopic depth perception all around an observer. An omnistereo projection on a cylindrical display does not require tracking of the observer's viewing direction. However,...
How does presentation method and measurement protocol affect distance estimation in real and virtual environments?
Timofey Y. Grechkin, Tien Dat Nguyen, Jodie M. Plumert, James F. Cremer, Joseph K. Kearney
Article No.: 26
We conducted two experiments that compared distance perception in real and virtual environments in six visual presentation methods using either timed imagined walking or direct blindfolded walking, while controlling for several other factors that...
Numerous image processing and computer graphics methods make use of either explicitly computed strength of image edges, or an implicit edge strength definition that is integrated into their algorithms. In both cases, the end result is highly...
