1. A method of processing computed tomography (CT) data for objects in a region comprising:

  • identifying a plurality of volume elements associated with a plurality of objects in the CT data, each volume element being associated with a density value;

    computing (a) a distance between a first object and a second object, (b) a first density associated with the first object and a second density associated with a second object, (c) a difference between the first density and the second density; and

    combining the first object and the second object into a single combined object if the difference between the first density and the second density is below a predetermined density difference threshold and the distance between the first object and the second object is below a predetermined distance threshold.
