The time evolution of the morphology of homogeneous phases during spinodal
decomposition is described using a family of morphological measures known as
Minkowski functionals. They provide the characteristic length scale
L of patterns in a convenient, statistically robust,
and computationally inexpensive way. They also allow one to
study the scaling behavior of the content, shape, and connectivity of
spatial structures and to define the crossover from the early
stage decomposition to the late stage domain growth.
We observe the scaling behavior 
with 
,
, and 
depending on the viscosity of the fluid.
When approaching the spinodal density 
, we recover the prediction
for the early time spinodal decomposition.
