Perceived transparency of neutral density filters across dissimilar backgrounds.
We examine how the luminance distributions of overlaid surfaces affect the perception of transparency of neutral density filters. Pairs of neutral density filters were generated overlying variegated backgrounds of varying luminance distributions, and observers adjusted a single parameter of one filter until the pair appeared equally transparent. Physically identical filters appeared equally tra...
متن کاملEmotionally Neutral Stimuli Are Not Neutral in Schizophrenia: A Mini Review of Functional Neuroimaging Studies
Reliable evidence shows that schizophrenia patients tend to experience negative emotions when presented with emotionally neutral stimuli. Similarly, several functional neuroimaging studies show that schizophrenia patients have increased activations in response to neutral material. However, results are heterogeneous. Here, we review the functional neuroimaging studies that have addressed this re...
متن کاملA Comparison of the Effects of Neutral Density Filters and Diffusing Filters on Motion Detection Perimetry, White-on-white Perimetry and Frequency Doubling Perimetry
Background: Motion detection perimetry and frequency doubling perimetry are methods that have been developed with the goal of detecting glaucomatous field defects earlier than conventional white-on-white perimetry. It is well recognized that the development of cataract and pupillary constriction can significantly influence perimetric thresholds when screening for, or following the progression o...
متن کاملPatch-Based Occlusion Culling for Hardware Tessellation
We present an occlusion culling algorithm that leverages the unique characteristics of patch primitives within the hardware tessellation pipeline. That is, unseen patches are costly to compute, but easy to find screen space bounds for. Our algorithm uses the well known hierarchical Z-buffer approach, but we present a novel variant that uses temporal coherence to maintain lists of visible and oc...
متن کاملVisual adaptation to interocular brightness differences induced by neutral-density filters.
PURPOSE Interocular brightness differences such as those caused by asymmetrical cataract have been found to have a minimal effect on interocular brightness matches. In the present study, the measured binocular visual response to interocular differences in retinal illuminance was measured over time. METHODS Interocular differences in retinal illuminance of magnitudes 0.3, 0.6, and 0.9 log unit...
