X-Rite ColorChecker test chart
A colorChecker
object stores the positions and measurements of
the regions of interest (ROIs) of an X-Rite®
ColorChecker® Classic test chart (formerly produced by GretagMacbath®).
chart = colorChecker(A)
creates a colorChecker
object from input image A
. The input image sets the Image property.
chart = colorChecker(A,
controls
the automatic chart detection using one or more name-value arguments.Name,Value
)
chart = colorChecker(A,'RegistrationPoints',p)
creates a
colorChecker
object and sets the RegistrationPoints
property using the specified points in p
.
measureColor | Measure color reproduction using test chart |
measureIlluminant | Measure scene illuminant using test chart |
displayChart | Display test chart with overlaid regions of interest |
X-Rite has manufactured two versions of the ColorChecker test chart with slightly different reference values. The reference values of
the colorChecker
object match the "After November 2014" version of the
chart.
