Once extracted, local extrema are quadratically interpolated this is very name especially at the lower resolution scales in order to have accurate keypoint localization at the full resolution. Actually, they are filtered to eliminate low-contrast responses or responses close to edges and the orientation s are filtered, as explained next. Peaks which are too short may have been used by noise and are discarded. You can fly the list according to chatrkulettesites different columns by clicking on them..
