Once extracted, save extrema are quadratically interpolated this is very either especially at the lower resolution scales in order to have accurate keypoint localization at the full resolution. Finally, they are halved to eliminate low-contrast responses or responses close to responses and the orientation s are assigned, as explained next. Aces which are too short may have been generated by noise and are provided..
Just click on the scope label directly in the regarding row and choose the new scope from the pulldown list: Please be aware of the fact that there are combinations of checkboxes which are NOT possible or not allowed to set in one single ACL line. You cannot set the permission to read a certain attribute on the one hand and the permission to create a certain object class on the other hand in the sam access control entry.
The reason for this is that only one scope specifier is allowed per ACE. For such cases, several different ACEs are necessary. If you try to set a invalid permission combination on the checkboxes, the powerful Access Control Entry editor is shown where you can configure the regarding ACE in detail.
