Laplacian Irregular Graph Pyramid
A Laplacian irregular graph pyramid was developed, which combines the principles of the Laplacian pyramid with the flexibility of the irregular graph pyramid. The Laplacian irregular graph pyramid allows to represent an image in multi-resolution while keeping the topological structures intact  (see publications).
