Figure 7.

Overlap between the salient features obtained for different views of an object. Several pairs/triplets of views of Object 1 and Object 2 are shown superimposed, together with their salient features, to allow appreciating whether, and to what extent, such features overlapped. The salient features are the same as those shown in Figure 6, only here are shown in either yellow or red, to distinguish the features obtained, respectively, for the default and the transformed views. The orange patches indicate the overlap between the salient features of two different views in a pair/triplet. A, Rat 5. B, Rat 2. C, Rat 3.
