Uncertainty and accuracy of vision-based tracking concerning stereophotogrammetry and noise-floor tests [PDF]

open access: yesMetrology and Measurement Systems, 2022
This work proposes a systematic assessment of stereophotogrammetry and noise-floor tests to characterize and quantify the uncertainty and accuracy of a vision-based tracking system.

A framework for the automation of testing computer vision systems [PDF]

open access: yesarXiv, 2021
Vision systems, i.e., systems that allow to detect and track objects in images, have gained substantial importance over the past decades. They are used in quality assurance applications, e.g., for finding surface defects in products during manufacturing, surveillance, but also automated driving, requiring reliable behavior. Interestingly, there is only

Detecting Cheating when Testing Vision:Variability in Acuity Measures Reveals Misrepresentation [PDF]

open access: yes, 2018
SIGNIFICANCE In certain scenarios, it is advantageous to misrepresent one's ability and "cheat" on vision tests. Our findings suggest that increased variability when testing visual acuity holds promise as a novel means to help detect this cheating and ...

Vision-Based Mobile App GUI Testing: A Survey [PDF]

open access: yesarXiv, 2023
Graphical User Interface (GUI) has become one of the most significant parts of mobile applications (apps). It is a direct bridge between mobile apps and end users, which directly affects the end user's experience. Neglecting GUI quality can undermine the value and effectiveness of the entire mobile app solution.

Color space distortions in patients with type 2 diabetes mellitus [PDF]

open access: yes, 2006
Color vision impairment was examined in patients with type 2 diabetes mellitus (DM2) without retinopathy. We assessed the type and degree of distortions of individual color spaces. DM2 patients (n = 32), and age-matched controls (n = 20)were tested using

Vision tests of sensory judges - review [PDF]

open access: yes, 2020
In sensory examinations, judges must be in good general health. They should not have any deficiencies that could affect their perception or adversely affect their sensory performance, and thus can affect the reliability of their judgments.

Agnosic vision is like peripheral vision, which is limited by crowding [PDF]

open access: yes, 2017
Visual agnosia is a neuropsychological impairment of visual object recognition despite near-normal acuity and visual fields. A century of research has provided only a rudimentary account of the functional damage underlying this deficit.

Colour vision: A review of the Cambridge Colour Test and other colour testing methods

open access: yesAfrican Vision and Eye Health, 2015
The evaluation of colour vision and discrimination of an individual forms an integral part of a routine eye and vision examination. With the increasing prevalence of inherited colour vision deficiencies, defects of colour vision can be detected in an ...
