PURPOSE: To study the distribution of ocular higher-order aberrations (HOAs) in a myopic
population and to assess the repeatability of HOA measurements determined by a …

Introduction. The wavefront aberration function is one of the most informative descriptors of
optical performance, and new techniques have recently been developed to measure this …

We have constructed a wave-front sensor to measure the irregular as well as the classical
aberrations of the eye, providing a more complete description of the eye's aberrations than …

The human visual system (HVS) is highly non-uniform in sampling, coding, processing and
understanding. The spatial resolution of the HVS is highest around the point of fixation …

Analysis was undertaken of the retinal image characteristics of the best-spectacle corrected
eyes of progressing myopes (n= 20, mean age= 22years; mean spherical equivalent=− 3.84 …

With rapidly advancing computer and network technologies, various visual signals
(including image, video, graphics, animation, etc.) are produced, and visual quality of …

Retinal image quality assessment (RIQA) is an essential step in automated screening
systems to avoid misdiagnosis caused by processing poor quality retinal images. A no …

Purpose: To explore whether subtle changes in visual quality can be detected using different
measures of visual function against the quick contrast sensitivity function test (quick CSF) …

Various ocular diseases, such as cataract, diabetic retinopathy, and glaucoma have affected
a large proportion of the population worldwide. In ophthalmology, fundus photography is …

This paper presents a full-reference image quality estimator based on color, structure, and
visual system characteristics denoted as CSV. In contrast to the majority of existing methods …
