Fig. 1 Top: multi-scale line/edge detection in the case of a mug with, from left to right, fine to coarse scales
Fig. 2 Dynamic routing principle: a keypoints in scale space plus the central keypoint (CKP) at the coarsest scale, b the routing represen-tation using the CKP and the highest saliency map peak (SMP) for the initial routing with translation (T), rotation
Fig. 3 Dynamic routing scheme with spreading and grouping: at top-left, central keypoints of template and input object excitate cells at intermediate levels through axonic fields, spreading activations in separate top-down (solid circle) and bottom-up (ope
