Figure 3: The image space, R (depicted here as 3-dimensional, to facilitate visualization), and some of its subspaces (see section 4.1). Two exemplars, E11 and E12, belong to the same class C1 (the class of 4-legged animal shapes). Some of the different views of E11 are shown (marked by open circles), along with its view space, V1. The surface patch represents a part of the shape space S; the view spaces of the individual objects are transverse to it. A morphing sequence originating at E12 and leading to two other shapes is illustrated by the dashed curve contained in S. Movement towards the upper right corner of S corresponds to a reduction in the resemblance between the resulting image and the images of coherently looking objects.
