The empirical characteristics of human pattern vision defy theoretically-driven expectations.

open access: yesPLoS Computational Biology, 2018
Contrast is the most fundamental property of images. Consequently, any comprehensive model of biological vision must incorporate this attribute and provide a veritable description of its impact on visual perception.

Acuity and contrast sensivity of infant vision

open access: yesNature, 1974
IF we are to study the development of form and space perception in man, it is necessary to know something of the basic visual capabilities of the developing human infant. There have been a number of investigations of visual acuity in the first few months of life.
