[HTML][HTML] A 'dipper'function for texture discrimination based on orientation variance

M Morgan, C Chubb, JA Solomon - Journal of vision, 2008 - iovs.arvojournals.org
We measured the just-noticeable difference (JND) in orientation variance between two
textures (Figure 1) as we varied the baseline (pedestal) variance present in both textures …

[HTML][HTML] Interaction of luminance and higher-order statistics in texture discrimination

JD Victor, C Chubb, MM Conte - Vision Research, 2005 - Elsevier
Most studies of texture processing are based on textures in which individual pixel statistics
are varied and spatial correlations are absent (“IID textures”), or textures in which spatial …

[HTML][HTML] Texture space

R Gurnsey, DJ Fleet - Vision research, 2001 - Elsevier
Many previous studies have examined the ease with which two spatially adjacent textures
can be segmented. Our goal is to examine the representational system that determines the …

Spatial variability as a limiting factor in texture-discrimination tasks: implications for performance asymmetries

BS Rubenstein, D Sagi - JOSA A, 1990 - opg.optica.org
Texture-discimination tasks reveal a pronounced performance asymmetry depending on
which texture represents the foreground region (small area) and which represents the …

[HTML][HTML] Variance of high contrast textures is sensed using negative half-wave rectification

C Chubb, JH Nam - Vision research, 2000 - Elsevier
A rectifying transformation is required to sense variations in texture contrast. Various
theoretical and practical considerations have inclined researchers to suppose that this …

Psychophysical evidence for global feature processing in visual texture discrimination

T Caelli, B Julesz - JOSA, 1979 - opg.optica.org
By defining texture as a global feature attained by integration over the image domain, we
show that texture discrimination can be predicted for a special class of visual textures …

Asymmetries in visual texture discrimination

R Gurnsey - Spatial Vision, 1989 - brill.com
Recent results have shown that texture discrimination is an asymmetrical process; texture A
within texture B may be much easier to detect than texture B within texture A. Two questions …

[HTML][HTML] A visual mechanism tuned to black

C Chubb, MS Landy, J Econopouly - Vision research, 2004 - Elsevier
Chubb et al.[Journal of the Optical Society of America A 11 (1994) 2350] investigated
preattentive discrimination of achromatic textures comprising random mixtures of 17 Weber …

Sensitivity for structure gradient in texture discrimination tasks

HC Nothdurft - Vision research, 1985 - Elsevier
Recent experiments indicate that the segregation of visual structures (“texture
discrimination”) depends not only on the form of texture elements but also on their spacing …

Examining edge-and region-based texture analysis mechanisms

SS Wolfson, MS Landy - Vision research, 1998 - Elsevier
Instantaneous texture discrimination performance was examined for different texture stimuli
to uncover the use of edge-based and region-based texture analysis mechanisms. Textures …
