Subsequently, in the sketch of the basic algorithm (Figure 6), the set of distractors should be redefined as follows: That is, the distractor set is restricted to those vertices n in the scene graph G that currently are at least as salient as the target object v. For target objects that are linguistically salient, this will typically lead to a reduction of the distractor set.
distinguishing graphs for these target objects will generally be smaller than those for nonsalient objects.
