Shape-based ordering of objects: We generate two artificial datasets each consisting of a reference object and its random deformations. Samples from the datasets are shown in (a) and (b). The binary images to the very left show the reference objects for each dataset. We then ordered all the deformed objects with respect to the nWESD scores between the object and the reference. The graphs in (c) and (d) plot these orderings. Based on visual inspection the ordering is quite reasonable.
