The visual perception of metal

Journal of Vision, 2018
The present research was designed to examine how the presence or absence of ambient light influences the appearance of metal. The stimuli depicted three possible objects that were illuminated by three possible patterns of illumination. These were generated by a single point light source, two rectangular area lights, or projecting light onto a ...

Developmental Eye Movement (DEM) and King-Devick (K-D) Performance in Multiple Sclerosis

Brain Sciences, 2022
Eye movement disorders have been reported in patients with multiple sclerosis (MS) as saccadic disturbances. Several methods have been described for the assessment of saccades, including the K-D and DEM tests. The performance of these tests also involves

Parking and the visual perception of space [PDF]

, 2009
Using measured data we demonstrate that there is an amazing correspondence among the statistical properties of spacings between parked cars and the distances between birds perching on a power line. We show that this observation is easily explained by the

Human‐like evaluation method for object motion detection algorithms

IET Computer Vision, 2020
This study proposes a new method to evaluate the performance of algorithms for moving object detection (MODA) in video sequences. The proposed method is based on human performance metric intervals, instead of ideal metric values (0 or 1) which are ...

Visual Perception as Patterning: Cavendish against Hobbes on Sensation [PDF]

, 2016
Many of Margaret Cavendish’s criticisms of Thomas Hobbes in the Philosophical Letters (1664) relate to the disorder and damage that she holds would result if Hobbesian pressure were the cause of visual perception. In this paper, I argue that her “two men”
