The importance of measuring contrast sensitivity in cases of visual disturbance.
GB Arden - British Journal of Ophthalmology, 1978 - bjo.bmj.com
A description is given of a practical clinical test of contrast sensitivity and of the results
obtained on a normal population. An account is given of recent physiological work which …

Theory of edge detection
D Marr, E Hildreth - Proceedings of the Royal Society of …, 1980 - royalsocietypublishing.org
A theory of edge detection is presented. The analysis proceeds in two parts.(1) Intensity
changes, which occur in a natural image over a wide range of scales, are detected …

Contrast masking in human vision
Contrast masking was studied psychophysically. A two-alternative forced-choice procedure
was used to measure contrast thresholds for 2.0 cpd sine-wave gratings in the presence of …

Feature detection in human vision: A phase-dependent energy model
This paper presents a simple and biologically plausible model of how mammalian visual
systems could detect and identify features in an image. We suggest that the points in a …

Lateral interactions between spatial channels: suppression and facilitation revealed by lateral masking experiments
We measured contrast detection thresholds for a foveal Gabor signal flanked by two high
contrast Gabor signals. The spatially localized target and masks enabled investigation of …

Contrast constancy: deblurring in human vision by spatial frequency channels.
MA Georgeson, GD Sullivan - The Journal of physiology, 1975 - Wiley Online Library
The perception of contrast was measured in humans by a technique of subjective contrast‐
matching, and was compared with contrast sensitivity as defined by threshold measures. 2 …

Human observer detection experiments with mammograms and power‐law noise
AE Burgess, FL Jacobson, PF Judy - Medical physics, 2001 - Wiley Online Library
We determined contrast thresholds for lesion detection as a function of lesion size in both
mammograms and filtered noise backgrounds with the same average power spectrum …

[PDF][PDF] The Gaussian derivative model for spatial vision. I- Retinal mechanisms
R Young - Spatial vision, 1987 - researchgate.net
Physiological evidence is presented that visual receptive fields in the primate eye are
shaped like the sum of a Gaussian function and its Laplacian. A new'difference-of-offset …
