...More detailed discussion about enforcing the separation between the features, sampling of the scale space and improvement in feature localization can be found in [ 8 , 4]. Once the location and scale have been assigned to candidate keypoints, the dominant orientation is computed by determining peaks in the orientation histogram of its local neigh-Figure 1. Examples of scale invariant keypoints....

...Commonly used representations are responses to a banks of filters [17], multi-dimensional histograms [12, 7], local Fourier-transforms [15] and affine invariant feature descriptors [ 8 ]....

...Our approach is motivated by the recent advances in object recognition using local scale invariant features proposed by [ 8 ] and adopts the strategy for localization by means of location recognition....
