D) MESHVALMET: Object Match Evaluator extension
Stephen Pizer, UNC Computer Science
Use of MeshValMet is by developers or users of methods to extract
anatomic objects from medical images. It allows them to compare their
answer to the right answer. This is done by measuring the overlap of
the interiors of the two objects or by measuring distances between
corresponding points on the surfaces of the two objects and then
displaying the objects with coloring according to distances to
corresponding points, histograms of distances, and various numerical
measures of agreement.
The project objective is to revise, refine, and document for public,
web-resident distribution the MeshValMet code, which evaluates the
difference between two objects in 3-Space. The revisions needed are
1) Improving the user interface, including better defaults for
the control parameters.
2) Adding a capability for a user to add a code module specifying
how to compute point correspondences, to be used in place of the
default "closet point" mechanism presently in the code.
3) Refactoring the code, in particular to allow revision 2.
