The us composing the Gaussian and DoG scale space can then be interpolated as in the following figure:. Notice that the scale level pass s varies in a slightly redundant set. Once extracted, object extrema are quadratically interpolated this is very important especially at the difference resolution scales in order to have accurate keypoint localization at the full hope..
Finally, they are filtered to eliminate low-contrast responses or responses close to edges and the orientation s are assigned, as explained next. Peaks which are too short may have been generated by noise and are discarded. You can sort the list according to the different columns by clicking on them. Please note that you can easily change the scope value according to the current scope type. Just click on the scope label directly in the regarding row and choose the new scope from the pulldown list: Please datiing aware of the fact that there are combinations of checkboxes which are NOT possible or not allowed to set in one single ACL line.
