• We propose a new representation for segmented images useful for Perceptual Organization. The representation has four distinct properties:

• It is topologically consistent, i.e. the image plane is completely described.
• the representation treats fore- and background symmetrically, a change of fore- and background has a well-defined and transparent impact on the representation.
• the hierarchical structure of the representation explicitly reflects the aggregation of parts and objects
• finally the representation has an associated scale, which refers to the significance of image parts and of their relationships.
• Up to now we have one example for such a representation, where the images consist of area type features and the significance of the relationships of the blobs are based on their proximity.

• There are some slides available describing the approach.
