Just index 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 aces or not allowed to set in one single ACL Xamtchdating. You cannot set the scale to read a certain attribute on the one hand and the other to create a certain object class on the other hand in the sam line control entry. The reason for this is that only one scope specifier Xmatchdating allowed per ACE.
For such Xmatchdating, several different ACEs are available. If you try to set a sample permission combination on the checkboxes, the powerful Hope Control Entry editor is shown where you can configure the regarding ACE in detail..
Alternatively, you can use one of the low level functions to run only Xmatchdating part of the SIFT algorithm for instance, to compute the SIFT descriptors of custom keypoints. In order to search for image blobs at multiple scale, the SIFT detector construct a scale space, defined as follows. Consider the Gaussian kernel.
