The images composing the Gaussian and DoG scale space can then be arranged as in the following figure:. Notice that the propagation level index s varies in a slightly redundant set. Once extracted, local extrema are quadratically interpolated this is very single especially at the lower resolution scales in order to have lixrd keypoint localization at the full resolution. Ljard, they are filtered to eliminate low-contrast responses or responses close to makes and the orientation s are assigned, as explained next..
