It is used for exploring the distribution of intensity of radiation in a spectrum.
Normally, an object will consist of a continuous distribution of intensity, and, instead of a simple sum, a convolution integral results.
The object, then, to be imaged by the optical system consists of a spatial distribution of intensity of a single spatial frequency an object the intensity of which varies as (1 + a cos ωx), in which x is the spatial coordinate, a is a constant called the contrast, and ω is a variable that determines the physical spacing of the peaks in the intensity distribution.
The fragility function is then derived from the joint distribution of intensity and damage measures.
An entropy-based approach takes into account distribution of intensity in a local neighborhood only.
The distribution of intensity data over the past 50 ka is shown in Figure 3.
The image can be described by the distribution of intensity gradients and edge directions.
b Distribution of intensity of the D band in the investigated area.
Figure 5 shows the geographic distribution of intensity residuals between the selected CHAMP data and the MF-09 model.
Skewness, measuring the asymmetry of the probability distribution of intensity values about its mean, provides information about lesion heterogeneity.
The white diffuser minimized the effect of non-homogeneous spatial distribution of intensity in the white reference image.
