Glass Patterns (GP)
A Glass pattern is the superposition of two
random point sets S1 and S2, where S2 is obtained
from S1 by means of a small geometric
transformation.
3
A vector field v(r) is associated to a GP, by
joining each point of S1 with the corresponding
point of S2

Continous Glass Patterns (CGP)
Generalization of the GP formalism to the
continous case
A CGP G(r) is defined as the max of z(r) over an
arc A(r) of streamline of v(r)
5
Cross-CGP
A cross-CGP C(r) transfers the microstructure of
a GP to an input image I(r)
