Introduction to special issue SAP 2012
Rachel McDonnell, Veronica Sundstedt
Article No.: 10
DOI: 10.1145/2325722.2325723

Which facial profile do humans expect after seeing a frontal view? a comparison with a linear face model
Matthaeus Schumacher, Volker Blanz
Article No.: 11
DOI: 10.1145/2325722.2325724

Manipulated versions of three-dimensional faces that have different profiles, but almost the same appearance in frontal views, provide a novel way to investigate if and how humans use class-specific knowledge to infer depth from images of faces....

Single-trial EEG classification of artifacts in videos
Maryam Mustafa, Stefan Guthe, Marcus Magnor
Article No.: 12
DOI: 10.1145/2325722.2325725

In this article we use an ElectroEncephaloGraph (EEG) to explore the perception of artifacts that typically appear during rendering and determine the perceptual quality of a sequence of images. Although there is an emerging interest in using an...

Visual and emotional salience influence eye movements
Yaqing Niu, Rebecca M. Todd, Matthew Kyan, Adam K. Anderson
Article No.: 13
DOI: 10.1145/2325722.2325726

In natural vision both stimulus features and cognitive/affective factors influence an observer's attention. However, the relationship between stimulus-driven (bottom-up) and cognitive/affective (top-down) factors remains controversial: How well...

Minification affects verbal- and action-based distance judgments differently in head-mounted displays
Ruimin Zhang, Anthony Nordman, James Walker, Scott A. Kuhl
Article No.: 14
DOI: 10.1145/2325722.2325727

Numerous studies report that people underestimate egocentric distances in Head-Mounted Display (HMD) virtual environments compared to real environments as measured by direct blind walking. Geometric minification, or rendering graphics with a...

Perception of blending in stereo motion panoramas
Vincent Couture, Michael S. Langer, Sébastien Roy
Article No.: 15
DOI: 10.1145/2325722.2325728

Most methods for synthesizing panoramas assume that the scene is static. A few methods have been proposed for synthesizing stereo or motion panoramas, but there has been little attempt to synthesize panoramas that have both stereo and motion. One...
