ACM Transactions on Applied Perception (TAP), Volume 7 Issue 4, July 2010

Editorial -- APGV 2010 special issue
Katerina Mania, Martin S. Banks
Article No.: 21

The saliency of anomalies in animated human characters
Jessica Hodgins, Sophie Jörg, Carol O'Sullivan, Sang Il Park, Moshe Mahler
Article No.: 22
DOI: 10.1145/1823738.1823740

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...

Perceptually motivated guidelines for voice synchronization in film
Elizabeth J. Carter, Lavanya Sharan, Laura Trutoiu, Iain Matthews, Jessica K. Hodgins
Article No.: 23
DOI: 10.1145/1823738.1823741

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
DOI: 10.1145/1823738.1823742

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
DOI: 10.1145/1823738.1823743

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
DOI: 10.1145/1823738.1823744

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...

Visually significant edges
Tunç Ozan Aydin, Martin Čadík, Karol Myszkowski, Hans-Peter Seidel
Article No.: 27
DOI: 10.1145/1823738.1823745

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...
