1. A method comprising:

  • obtaining input image data defining an input image set that shows an input node-link structure;

    the input image set showing a set of nodes that satisfy a constraint on nodes and a set of links that satisfy a constraint on links;

    the input node-link structure satisfying a constraint on node-link structures;

    using the input image data to obtain likely node-link data;

    the likely node-link data indicating a first set of parts of the input image set that satisfy the constraint on nodes and indicating a second set of parts of the input image set that satisfy the constraint on links; and

    using the likely node-link data to obtain constrained node-link data, the constrained node-link data indicating a subset of the first set of parts and indicating a subset of the second set of parts, the subsets of the first and second sets of parts satisfying the constraint on node-link structures.
