Name
SkeletonQuality (SkeletonQualityDisplay) — Color each element according to its effective energy.
Synopsis
SkeletonQualityDisplay(alpha, colormap, min, max)
Details
-
Base class:
DisplayMethod -
Parameters:
alpha- alpha controls the relative importance of element shape and homogeneity. alpha=0 emphasizes shape and ignores homogeneity. alpha=1 emphasizes homogeneity and ignores shape. Type: A real number in the range [0, 1].
colormap- color scheme Type: An object of the
ColorMapclass. min- lowest energy to display, or 'automatic' Type: An integer, a real number, or the value
automatic. max- highest energy to display, or 'automatic' Type: An integer, a real number, or the value
automatic.
Description
SkeletonQualityDisplay fills each Skeleton
Element with a single color, determined by the effective energy of the
Element.
The alpha parameter controls the relative
importance of shape and
homogeneity
when computing the energy.
The colormap argument governs the translation
from scalar values to colors.
min and max determine the
range of energies to display. They should be real numbers between
0 and 1, or the special object automatic.
If they're set to automatic, the limits
will be determined by the extremes of the data.
Figure 6.103. The Skeleton Quality Display
(a) A Skeleton for a Microstructure with three types of pixels. The
initial 10×10 rectangular grid has been refined twice by Bisection with
alpha=0.3.
(b) The SkeletonQualityDisplay with
alpha=0 and the ThermalMap color map with
min = max = automatic. The scale (on the right)
goes from 0 (black) to 0.64 (white). Because
alpha=0 the energy depends only on shape, so the
poorly shaped Elements are highlighted.
(c) The same display, but with alpha=0.8. The
inhomogeneous Elements and the poorly shaped Elements are both
highlighted. The color scale goes from 0 (black) to 0.46
(white).
(d) The same display, again, but with alpha=1.
Only the homogeneity contributes to the energy, so only the
inhomogeneous Elements are colored. The color scale goes from
0 (black) to 0.50 (white).
