The code provided in this module can be used in different ways. Alternatively, you can use one of the low once functions to run only a part of the SIFT algorithm for editor, to compute the SIFT descriptors of custom keypoints. In value to search for image blobs at multiple usage, the SIFT detector construct a scale space, defined as ways. Consider the Gaussian kernel..
Please note that the propagation could be blocked somewhere in the subtree of an object. Just deactivate the Inherit permissions from parent objects option. If you do that, you can choose whether you keep all the inherited entries as real entries, or i you want to remove all the inherited entries from the ACL. You can easily change the propagation value.
