Filling-In and Suppression of Visual Perception from Context: A Bayesian Account of Perceptual Biases by Contextual Influences [PDF]
, 2008 Visual object recognition and sensitivity to image features are largely influenced by contextual inputs. We study influences by contextual bars on the bias to perceive or infer the presence of a target bar, rather than on the sensitivity to image ...

Preoperative corneal astigmatism among adult patients with cataract in Northern Nigeria
Indian Journal of Ophthalmology, 2014 The prevalence and nature of corneal astigmatism among patients with cataract has not been well-documented in the resident African population. This retrospective study was undertaken to investigate preexisting corneal astigmatism in adult patients with ...

High and low contrast acuity and clinical contrast sensitivity tested in a normal population
, 1989 Visual acuities obtained with a high contrast Bailey-Lovie chart (HCBL) and a low contrast Bailey-Lovie chart (LCBL) were compared with clinical contrast sensitivity function (CSF) measurements in a group of normal subjects with a wide range of ...

Measuring contrast sensitivity with inappropriate optical correction
, 2000 Spatial frequency-selective minima (notches) in the contrast sensitivity function (CSF) because of defocus can mimic those that occur with ocular disease. We examined the influence of measurement conditions on CSF shape in simulated clinical testing. CSF

The assessment of contrast sensitivity and contrast reserve for reading rehabilitation
, 1994 Several visual diseases not only reduce visual acuity, they also may impair a client’s ability to detect lower contrast objects that are well above acuity threshold.
