Eye Movements, Strabismus, Amblyopia and Neuro-Ophthalmology Perceived Visual Distortions in Juvenile Amblyopes During/Following Routine Amblyopia Treatment

by Marianne E F Piano , Peter J Bex , Anita J Simmers
"... PURPOSE. To establish the point prevalence of perceived visual distortions (PVDs) in amblyopic children; the association between severity of PVDs and clinical parameters of amblyopia; and the relationship between PVDs and amblyopia treatment outcomes. METHODS. Perceived visual distortions were meas ..."

Image Quality Assessment: From Error Visibility to Structural Similarity

by Zhou Wang, Alan C. Bovik, Hamid R. Sheikh, Eero P. Simoncelli - IEEE TRANSACTIONS ON IMAGE PROCESSING , 2004
"... Objective methods for assessing perceptual image quality have traditionally attempted to quantify the visibility of errors between a distorted image and a reference image using a variety of known properties of the human visual system. Under the assumption that human visual perception is highly adapt ..."

Efficient region tracking with parametric models of geometry and illumination

by Gregory D. Hager, Peter N. Belhumeur - PAMI , 1998
"... Abstract—As an object moves through the field of view of a camera, the images of the object may change dramatically. This is not simply due to the translation of the object across the image plane. Rather, complications arise due to the fact that the object undergoes changes in pose relative to the v ..."

for handling the geometric distortions produced by changes in pose. We then combine geometry and illumination into an algorithm that tracks large image regions using no more computation than would be required to track with no accommodation for illumination changes. Finally, we augment these methods

Illusion and well-being: A social psychological perspective on mental health.

by Shelley E Taylor , Jonathon D Brown , Nancy Cantor , Edward Emery , Susan Fiske , Tony Green-Wald , Connie Hammen , Darrin Lehman , Chuck Mcclintock , Dick Nisbett , Lee Ross , Bill Swann , Joanne - Psychological Bulletin, , 1988
"... Many prominent theorists have argued that accurate perceptions of the self, the world, and the future are essential for mental health. Yet considerable research evidence suggests that overly positive selfevaluations, exaggerated perceptions of control or mastery, and unrealistic optimism are charac ..."

that one takes or accepts the characteristics of nature, (p. so that one is able to take in matters one wishes were different without distorting them to fit these wishes. (1953, p. 349) Since Jahoda's report, the position that the mentally healthy person perceives reality accurately has been put

Video Quality Assessment Based on Structural Distortion Measurement

by Zhou Wang, Ligang Lu, Alan C. Bovik , 2004
"... Objective image and video quality measures play important roles in a variety of image and video processing applications, such as compression, communication, printing, analysis, registration, restoration, enhancement and watermarking. Most proposed quality assessment approaches in the literature are ..."

are error sensitivity-based methods. In this paper, we follow a new philosophy in designing image and video quality metrics, which uses structural distortion as an estimate of perceived visual distortion. A computationally e#cient approach is developed for full-reference (FR) video quality assessment

Prefuse: A toolkit for interactive information visualization

by Jeffrey Heer, Stuart K. Card, James A. Landay - In ACM Human Factors in Computing Systems (CHI , 2005
"... In this demonstration we present prefuse, an extensible user interface toolkit for building interactive information visualization applications, including node-link diagrams, containment diagrams, and visualizations of unstructured (edge-free) data such as scatter plots and timelines. prefuse data in ..."

The result is a platform for creating scalable, highly-interactive visualizations of large data sets in a modular and principled fashion. We have used prefuse to implement both novel

Image information and visual quality

by Hamid Rahim Sheikh, Alan C. Bovik - IEEE Trans. IP , 2006
"... Abstract—Measurement of visual quality is of fundamental importance to numerous image and video processing applica-tions. The goal of quality assessment (QA) research is to design algorithms that can automatically assess the quality of images or videos in a perceptually consistent manner. Image QA a ..."

Specifically, we propose to quantify the loss of image information to the distortion process and explore the relationship between image information and visual quality. QA

Dynamic binding in a neural network for shape recognition

by John E. Hummel, Irving Biederman - Psychological Review , 1992
"... Given a single view of an object, humans can readily recognize that object from other views that preserve the parts in the original view. Empirical evidence suggests that this capacity reflects the activation of a viewpoint-invariant structural description specifying the object's parts and the ..."

binding allows tremendous economy of representation and permits the representation to reflect the attribute structure of the shapes represented. A brief glance at Figure 1 is sufficient to determine that it depicts three views of the same object. The perceived equiva-lence of the object across its views

Forming impressions of personality

by S. E. Asch - Journal of Abnormal and Social Psychology , 1946
"... WE look at a person and imme-diately a certain impression ofhis character forms itself in us. A glance, a few spoken words are suf-ficient to tell us a story about a highly complex matter. We know that such impressions form with remarkable rapidity and with great ease. Subse-quent observation may en ..."
