Sentence examples for luminance of image from inspiring English sources

CIE-LUV color space has better robustness when the luminance of image has some changes compared with other color space.

The importance of phase of an image for its fidelity representation is well known, and the gradient of an image is an implication of changes in the luminance of an image.

where AvgInt is the average luminance of sub image and MedInt(I) is the average luminance of the whole image I. Contrast Metric.

The mean luminance of every image reflecting larval movement was quantified by automated counting of total dynamic pixels per image and plotted against time.

These statistics are mainly HVS-inspired features, namely, edge amplitude, edge length, background activity, and background luminance of an image.

Also, is the frequency sensitivity threshold, is the DC term of block, and is the average luminance of the image [21].

If AvgInt(S i ) is the average luminance of sub image   and AvgInt is the average luminance of all its surrounding subimages, then the contrast measure can be defined as (4).

The contrast for each grid cell was defined as a version of root-mean-square contrast: 26 the standard deviation of luminance values of all pixels in the grid cell divided by the mean luminance of the image.

While Michelson contrast was defined as the normalized difference between the highest and the lowest luminance of the image, the Fourier power spectrum provides a quantitative measure of the resolvable spatial frequency structures of the two images [ 18].

This finding supports the finding of Kromeier et al. [ 7, 8] that unequal luminance of the images for the two eyes does not necessarily influence the vergence position.

First, three common measures of local image statistics that characterize different properties of image luminance were examined: luminance, luminance contrast, and edge density.
