By analyzing the whole surface area,
coincidental errors in color data are avoided and shrinkage
does not influence the results of color measurements in the
way it would using a device with a defined detector area.
Furthermore, two-dimensional shrinkage (visible crosssection)
can be determined using the same image
Shrinkage, a and b as functions of time as well as the
correlations between the color values gained by colorimeter
and RGB images were best represented using linear fits. L
as a function of time followed a second-order polynomial
development and color parameters as functions of moisture
content X were best represented using third-order polynomial
fits
