All stimulus parameters including luminance and contrast should be calibrated either locally or by the manufacturer and regular recalibration is advised [ 3].
7, 8 The basic picture that emerged is that image features, including luminance, contrast, and edge density all differ between fixated locations and control locations.
In addition, the physical properties of the photographs are reported, including luminance, contrast, and entropy.
Additional physical qualities of the pictures, including luminance, contrast, and color composition are also provided.
In addition to the dimensional category ratings of valence and arousal, the authors have also provided the physical parameters of each picture, including luminance, contrast, and color composition.
In [7], multiple cues including color, luminance, and texture are applied to detect moving shadows.
More generally, the model should be extended to include mechanisms for luminance and contrast gain control (Mante et al., 2008), both of which are essential for natural vision.
Step two includes a luminance enhancement using modified Retinex and chrominance enhancement using enhancement map and histogram rescaling in color space CIELCh.
And PeLED parameters, including maximum luminance (Lmax) and maximum CE (CEmax) are summarized in Table 2.
Meteorological variables namely luminance distribution for the whole sky including zenith luminance, global, direct-beam and sky-diffuse illuminance on a horizontal surface and vertical sky illuminance, and horizontal and vertical solar irradiance data are adopted for analysis.
