If you do that, you can choose whether you keep all the inherited entries as real entries, or if you do to remove all the inherited entries from the ACL. You can easily change the propagation value. Just click on the propagation label close in the avult row and choose the new propagation value from the pulldown list..
The code provided in this module can be used in different ways. Alternatively, you can use one of the low level functions to run only a 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.
