Binocular summation of detection and resolution thresholds in the central visual field using parallel-line targets.
PURPOSE To investigate the effect of thresholds on binocular summation for detection and resolution of parallel-line targets of different widths. METHODS The automatic perimeter Octopus 201 (Haag-Streit International, Köniz, Switzerland) combined with a modified haploscope device and targets consisting of parallel lines that were 10' (10' target), 2.5' (2.5' target), or 1.43' (1.43' target) o...
متن کاملTime will tell: deficits of temporal information processing in patients with visual field loss.
Visual field loss after brain lesions is commonly determined using perimetric tests of light detection (perimetry). Many patients with visual field defects complain about perceptual difficulties in areas that are perimetrically normal. To look at a potential cause for such difficulties, we topographically determined temporal characteristics of visual information processing in those patients and...
متن کاملJust Noticeable Difference Estimation Using Visual Saliency in Images
Due to some physiological and physical limitations in the brain and the eye, the human visual system (HVS) is unable to perceive some changes in the visual signal whose range is lower than a certain threshold so-called just-noticeable distortion (JND) threshold. Visual attention (VA) provides a mechanism for selection of particular aspects of a visual scene so as to reduce the computational loa...
متن کاملResolution Acuity is better than Vernier Acuity
Our impressive sensitivity to vernier offsets as compared to resolution acuity has long inspired vision researchers to study the phenomena in great detail. In this study we use the test-pedestal framework to compare resolution and vernier acuity. In these experiments the test stimulus is the same for both tasks, only the pedestals differ. When thresholds are expressed in common units of test st...
متن کاملThe Comparative Development of Movement Hyperacuity and Visual Acuity in Children
Oscillatory movement displacement thresholds (OMDT) have been suggested as a test of neural integrity of the visual system, detecting deficit even in the presence of normal resolution. Both OMDT and visual resolution were measured in 153 normal children between the ages of 2.2 and 13 yr (mean = 6.2 +/- 2.8 yr). OMDT were obtained using a computer-generated vertical bar stimulus oscillating at 4...
متن کامل1437 A dissociation of perceptual organization based on proximity and similarity: A case study
-The alteration of contrast sensitivity function (C.S.F.) is known in Parkinson’s disease. The aim of this study is to determine if this alteration is present at early stages of the disease. Methods.Twelve parkinsonian patienls under dopatherapy and at early stages of the disease and twelve control subjects were tested. The C.S.F. test consisted of presentation on a high resolution. snap scanni...
