Evaluation of a multiscale color model for visual difference prediction
P. George Lovell, C. Alejandro Párraga, Tom Troscianko, Caterina Ripamonti, David J. Tolhurst
Pages: 155-178
DOI: 10.1145/1166087.1166089
How different are two images when viewed by a human observer? There is a class of computational models which attempt to predict perceived differences between subtly different images. These are derived from theoretical considerations of human...

Perceptual limits on 2D motion-field visualization
Michael S. Langer, Javeen Pereira, Dipinder Rekhi
Pages: 179-193
DOI: 10.1145/1166087.1166090
This paper examines perceptual issues in 2D motion-field visualization. Several aspects of motion-field perception are considered, including sensitivity to spatial gradients, number of motion layers, and motion blur. Our analysis concentrates on a...

Cognitive factors can influence self-motion perception (vection) in virtual reality
Bernhard E. Riecke, Jörg Schulte-Pelkum, Marios N. Avraamides, Markus Von Der Heyde, Heinrich H. Bülthoff
Pages: 194-216
DOI: 10.1145/1166087.1166091
Research on self-motion perception and simulation has traditionally focused on the contribution of physical stimulus properties (“bottom-up factors”) using abstract stimuli. Here, we demonstrate that cognitive (“top-down”)...

Exploring visual and automatic measures of perceptual fidelity in real and simulated imagery
Ann McNamara
Pages: 217-238
DOI: 10.1145/1166087.1166092
This paper introduces a new psychophysical experiment developed to enable observers to judge the quality of computer graphics imagery with respect to the real scene it depicts. This new framework facilitates perceptual judgment of images against a...

Object feature validation using visual and haptic similarity ratings
Theresa Cooke, Sebastian Kannengiesser, Christian Wallraven, Heinrich H. Bülthoff
Pages: 239-261
DOI: 10.1145/1166087.1166093
The perceived similarity between objects may well vary according to the sensory modality/modalities in which they are experienced, an important consideration for the design of multimodal interfaces. In this study, we present a similarity-based method...

Sketching shiny surfaces: 3D shape extraction and depiction of specular surfaces
Ulrich Weidenbacher, Pierre Bayerl, Heiko Neumann, Roland Fleming
Pages: 262-285
DOI: 10.1145/1166087.1166094
Many materials including water, plastic, and metal have specular surface characteristics. Specular reflections have commonly been considered a nuisance for the recovery of object shape. However, the way that reflections are distorted across the...

A perceptual framework for contrast processing of high dynamic range images
Rafal Mantiuk, Karol Myszkowski, Hans-Peter Seidel
Pages: 286-308
DOI: 10.1145/1166087.1166095
Image processing often involves an image transformation into a domain that is better correlated with visual perception, such as the wavelet domain, image pyramids, multiscale-contrast representations, contrast in retinex algorithms, and chroma,...

Methods for the assessment of fused images
T. D. Dixon, E. F. Canga, J. M. Noyes, T. Troscianko, S. G. Nikolov, D. R. Bull, C. N. Canagarajah
Pages: 309-332
DOI: 10.1145/1166087.1166096
The prevalence of image fusion---the combination of images of different modalities, such as visible and infrared radiation---has increased the demand for accurate methods of image-quality assessment. The current study used a signal-detection...
