Peeling Plaids Apart: Context Counteracts Cross-Orientation Contrast Masking [PDF]
, 2009 Background: Contrast discrimination for an image is usually harder if another image is superimposed on top. We asked whether such contrast masking may be enhanced or relieved depending on cues promoting integration of both images as a single pattern ...

The time course of adaptation to spatial contrast [PDF]
, 1991 We explored the buildup and decay of threshold elevation during and after adaptation to sinewave gratings in a series of experiments investigating the effects of adapting time, adapting contrast, spatial frequency and retinal eccentricity.

Contrast‐to‐noise ratios of diffusion anisotropy indices [PDF]
Magnetic Resonance in Medicine, 2005 AbstractThe degree of diffusion anisotropy in different brain regions is usually measured by a diffusion anisotropy index (DAI) such as relative anisotropy (RA) and fractional anisotropy (FA). FA has been reported to have a higher contrast‐to‐noise ratio (CNR) than RA. The present work compares the CNRs of seven DAIs in theoretical propagation‐of‐error

Binocular summation of contrast remains intact in strabismic amblyopia [PDF]
, 2007 PURPOSE. Strabismic amblyopia is typically associated with several visual deficits, including loss of contrast sensitivity in the amblyopic eye and abnormal binocular vision.

Contextual and variational contrast enhancement [PDF]
, 2011 This paper proposes an algorithm which enhances the contrast of an input image using inter-pixel contextual information. The algorithm uses a two-dimensional (2D) histogram of the input image constructed using mutual relationship between each pixel and ...
