Understanding deep features with computer-generated imagery Mathieu Aubry
"... We introduce an approach for analyzing the variation of features generated by convolutional neural networks (CNNs) with respect to scene factors that occur in natural images. Such factors may include object style, 3D viewpoint, color, and scene lighting configuration. Our approach analyzes CNN featu ..."

on large image datasets: AlexNet [18], Places [40], and Oxford VGG [8]. We observe important differences across the networks and CNN layers for different scene factors and object categories. Finally, we demonstrate that our analysis based on computer-generated imagery translates to the network
An Algorithm for Computer Generated Imagery and to Improve the General Quality of Image

The Development and Evaluation of a Model of Visual Acuity for Computer-Generated Imagery
, 1997
"... : This paper presents a model for human visual acuity which accommodates the effects of peripheral vision and target velocity. The model is based upon work from the field of visual perception in order to provide an accurate and principled result. The model is evaluated through a number of psychophys ..."

computer-generated scene. Keywords: contrast sensitivity, psychophysics, spatial frequency, threshold vision, visual acuity. 1 Introduction This paper is concerned with the task of predicting the visibility of any arbitrary stimulus on a computer display device. That is, to resolve whether a user can

Pyramidal parametrics
- Computer Graphics (SIGGRAPH ’83 Proceedings
, 1983
"... The mapping of images onto surfaces may substantially increase the realism and information content of computer-generated imagery. The projection of a flat source image onto a curved surface may involve sampling difficulties, however, which are compounded as the view of the surface changes. As the pr ..."

Locomotion mode affects the updating of objects encountered during travel: The contribution of vestibular and proprioceptive inputs to path integration. Presence: Teleoperators and Virtual Environments
- Presence
, 1998
"... In two experiments, subjects traveled through virtual mazes, encountering target objects along the way. Their task was to indicate the direction to these target objects from a terminal location in the maze (from which the objects could no longer be seen). Subjects controlled their motion through the ..."

. This process created the impression of immersion in the experimental maze. In the Visual Turn mode subjects moved through the environment using a joystick to control their turning. The only sensory information subjects received about rotation and translation was that provided by the computer-generated imagery
PHYSIOLOGICALLY-BASED DETECTION OF COMPUTER GENERATED FACES IN VIDEO
"... We describe a new forensic technique for distinguishing be-tween computer generated and human faces in video. This technique identifies tiny fluctuations in the appearance of a face that result from changes in blood flow. Because these changes result from the human pulse, they are unlikely to be fou ..."

All Aboard The Polar Express: A “Playful” Change of Address in the Computer-Generated Blockbuster’, animation: an interdisciplinary journal 1(2
, 2006
"... Abstract Following Tom Gunning’s assertion that each change in film history implies a change in its address to the spectator, this article closely analyses The Polar Express (Robert Zemeckis, 2004) in order to interrogate what kinds of changes are at stake for the contemporary spectator of the wholl ..."

Merging Virtual Objects with the Real World: Seeing Ultrasound Imagery within the Patient
, 1992
"... We describe initial results which show “live” ultrasound echography data visualized within a pregnant human subject. The visualization is achieved by using a small video camera mounted in front of a conventional head-mounted display worn by an observer. The camera’s video images are composite with c ..."

As the observer walks around the subject. the ultrasound images appear stationary in 3-space within the subject. This kind of enhancement of the observer’s vision may have
