This is a survey of psychophysical studies of motion perception carried out mainly in the last
10 years. It covers a wide range of topics, including the detection and interactions of local …

Visual detection and discrimination thresholds are often measured using adaptive
staircases, and most studies use transformed (or weighted) up/down methods with fixed step …

A contrast sensitivity function, or CSF, is a cornerstone of many visual models. It explains
whether a contrast pattern is visible to the human eye. The existing CSFs typically account …

The retinal ganglion cells (RGCs) receive different combinations of L, M, and S cone inputs
and give rise to one achromatic and two chromatic postreceptoral channels. The goal of the …

The contrast sensitivity function (CSF) is a fundamental visual model explaining our ability to
detect small contrast patterns. CSFs found many applications in engineering, where they …

Previous studies have generally estimated that two independent channels underlie human
temporal vision: one broad and low-pass, the other high, and band-pass. We confirm this …

When studying human ability to perceive temporal changes in luminance it is customary to
estimate either temporal impulse response shapes or temporal modulation transfer …

Uncomfortable images generally have a particular spatial structure, which deviates from a
reciprocal relationship between amplitude and spatial frequency (f) in the Fourier domain …

In this paper we argue that biological vision and electronic image acquisition share common
principles despite their vastly different implementations. These shared principles are based …

We studied scotopic motion mechanisms, using a two-frame sinusoidal grating separated by
various ISIs equated for mean luminance level. Perceived direction of displacement varied …
