Corner detection.

Figures 12-13 show the result of detecting corners in a closely related way, by detecting points at which the normalized measure of corner strength assumes a simultaneous local maximum over space and scale. Note in figure 13 that a coarse scale response is obtained for the large size corner structure as a whole, whereas finer-scale responses are obtained for the superimposed corner structures of smaller spatial extent.
