This paper investigates to what level viewers fail to notice degradations in image quality, between nontask related areas and task related areas, when quality parameters such as image resolution, edge antialiasing and reflection and shadows are altered.
Abstract
The perception of a virtual environment depends on the user and the task the user is currently performing in that environment. Models of the human visual system can thus be exploited to significantly reduce computational time when rendering high fidelity images, without compromising the perceived visual quality. This paper considers how an image can be selectively rendered when a user is performing a visual task in an environment. In particular, we investigate to what level viewers fail to notice degradations in image quality, between nontask related areas and task related areas, when quality parameters such as image resolution, edge antialiasing and reflection and shadows are altered.

A framework for visual saliency detection with applications to image thumbnailing

TL;DR: A novel framework for visual saliency detection based on a simple principle: images sharing their global visual appearances are likely to share similar salience, which outperforms state-of-the-art approaches.

Framework for image thumbnailing based on visual similarity

TL;DR: In this article, an apparatus and method for detecting a region of interest in an image is disclosed, where image representations for a set of images that have been manually annotated with regions of interest are stored, along with positive and negative representations of each image which are similarly derived to the image representations except that they are based on features extracted from patches within the region and outside it, respectively.

Visual attention in 3D video games

TL;DR: This paper presents results showing different visual attention patterns that players exhibit in two different game types: action-adventure games and first person shooter games.

Visual attention in 3D video games

TL;DR: Results from visual attention research are being adopted by computer graphics research to achieve real-time global illumination by concentrating the global illumination calculation only in parts of the scene that are salient.

Visual attention for efficient high-fidelity graphics

TL;DR: It is demonstrated that viewers performing a visual task within the environment consistently fail to notice the difference between high quality and selectively rendered images, computed in a significantly reduced time.

A model of saliency-based visual attention for rapid scene analysis

TL;DR: In this article, a visual attention system inspired by the behavior and the neuronal architecture of the early primate visual system is presented, where multiscale image features are combined into a single topographical saliency map.

Shifts in selective visual attention: towards the underlying neural circuitry.

TL;DR: This study addresses the question of how simple networks of neuron-like elements can account for a variety of phenomena associated with this shift of selective visual attention and suggests a possible role for the extensive back-projection from the visual cortex to the LGN.

A saliency-based search mechanism for overt and covert shifts of visual attention.

TL;DR: A detailed computer implementation of a saliency map scheme is described, focusing on the problem of combining information across modalities, here orientation, intensity and color information, in a purely stimulus-driven manner, which is applied to common psychophysical stimuli as well as to a very demanding visual search task.

Gorillas in our midst: sustained inattentional blindness for dynamic events.

TL;DR: A new study builds on classic studies of divided visual attention to examine inattentional blindness for complex objects and events in dynamic scenes and suggests that the likelihood of noticing an unexpected object depends on the similarity of that object to other objects in the display and on how difficult the priming monitoring task is.

The visible differences predictor: an algorithm for the assessment of image fidelity

Scott Daly
TL;DR: In this paper, an algorithm for determining whether the goal of image fidelity is met as a function of display parameters and viewing conditions is presented, which is intended for the design and analysis of image processing algorithms, imaging systems, and imaging media.
