Vection with large screen 3D imagery

Conference companion on Human factors in computing systems common ground - CHI '96, 1996
Vection is the illusory impression of self motion that can be obtained when an observer views a I,argescreen display containing a rotating or translating pattern. To aid in our construction of an interactive large screen interface to virtual 3D environments, we conducted studies to determine the factors which induce a sense of vection.

Persistent 3D stabilization for aerial imagery

2016 IEEE Winter Conference on Applications of Computer Vision (WACV), 2016
In this paper, we present a novel 3D stabilization method for aerial imagery. While most existing aerial surveillance applications rely on 2D stabilization, which generates parallax errors in urban scenes, we aim to compensate camera motion perfectly as if the scene had been captured by a static camera.

The Effects of 3D Imagery on Managerial Data Interpretation

MIS Quarterly, 1986
The new technology of computer graphics makes it possible to create images on the screen that literally appear to pop out into the room. This is accomplished by creating separate images for the left and right eye and filtering them so that each eye receives the appropriate image.

3D organization of 2D urban imagery

SPIE Proceedings, 2007
Working with New York data as a representative and instructive example, we fuse aerial ladar imagery with satellite pictures and Geographic Information System (GIS) layers to form a comprehensive 3D urban map. Digital photographs are then mathematically inserted into this detailed world space.

Perception of size and shape in stereoscopic 3D imagery

SPIE Proceedings, 2012
This paper explores the mathematical relationships between the scene geometry, camera parameters, and viewing environment and their influence on the viewer's perception of 3D. The current practice of using horizontal image translation to set convergence has an effect on the shape ratio and 3D magnification factor of the resulting images and is not ...

Controlling Miniaturization in Stereoscopic 3D Imagery

SMPTE Motion Imaging Journal, 2013
Viewers of stereoscopic three-dimensional (3D) imagery can perceive the absolute size of objects within a scene. On larger screens, the perceptual size of objects commonly appears bigger than reality, which matches viewers’ expectations for big-screen, larger-than-life theatrical experiences.

Performances of the 3D-SAR imagery

Proceedings of IGARSS '94 - 1994 IEEE International Geoscience and Remote Sensing Symposium, 2002
The use of multitemporal SAR data has been in recent years the biggest advance in radar remote sensing. Interferometry was the first application, followed by radiometric resolution and then geometric resolution enhancement, and finally, as a consequence, lay-over attenuation.

Interactive, knowledge-guided visualization of 3D medical imagery

Future Generation Computer Systems, 1999
Abstract One of the most important and difficult decision-making tasks is that of interpreting three-dimensional (3D) medical imagery. This information-intensive task typically requires expediency, accuracy and reliability in both the visual presentation as well as in the interpretation of complex information.

3D Eye Tracking for Visual Imagery Measurements

2019
Experiences of visual imagery, the ability to see in the mind’s eye, occur in various situations. The Vividness of Visual Imagery Questionnaire (VVIQ) has been widely used to subjectively measure the vividness of visualizers based on its score. For objective measurements, studies show that functional Magnetic Resonance Imaging (fMRI) can be used to ...
