  1. Glass Patterns and Artistic Imaging Giuseppe Papari and Nicolai Petkov

  2. Glass Patterns (GP) S1 S2 (rotated S1) S1 S2 (GP) S1 S2 (scaled S1) S1 S2 (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

  4. Continous Glass Patterns (CGP) z(r) Examples of CGP associated to different vector fields v(r) 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) Input image I(r) Examples of cross-CGP
