Sentence examples for sensitivity of luminance from inspiring English sources

A previous study indicates that the contrast sensitivity of luminance grating for that direction is reduced during pursuit [20].

The sensitivity of luminance channel differs between retinal locations, due mainly to the nonuniformity of ocular media such as macular pigment.

The aim of this study was to measure visual contrast sensitivity (CS) of luminance using vertical sinusoidal gratings with spatial frequencies of 0.6, 2.5, 5.0 and 20.0 cycles per degree of visual angle in chronic alcoholics in abstinence period.

In the proposed DFIS, as it is shown in Figure 1, the inputs consist of texture sensitivity, luminance sensitivity, and location sensitivity parameters of each block and the outputs consist of corresponding suitability and weighting factors.

It takes into account human's ability to adapt to a structural similarity at different scales and HVS sensitivity to distortions of luminance and contrast.

Spatial contrast sensitivity The contrast sensitivity function (CSF) measures the sensitivity to luminance gratings as a function of spatial frequency, where sensitivity is defined as the inverse of the threshold contrast.

For the investigation of luminance contrast sensitivity, we used sinusoidal gratings at several spatial frequencies as stimuli to detect the contrast threshold.

All these findings indicated that psychophysical evaluation of luminance contrast sensitivity and colour vision are important tools for the screening of visual function deficits in diabetic patients, but there are some aspects that need further clarification.

These observations indicate that the log, PU, and PQ domains can better represent the luminance sensitivity of the HVS than the linear domain, but they might not be optimal for the chrominance sensitivity.

It denotes the variations in the sensitivity depend on the local mean of luminance component in color images.

The visual deficits in processing of luminance contrast and motion sensitivity were originally interpreted as evidence of an impairment in the transient visual system rather than in the sustained system [ 6].
