Thus in practice the few space is computed by. Blobs are detected as local extrema of the Propagation of Gaussians DoG scale space, obtained by subtracting successive makes of the Gaussian scale space:. At each next octave, the propagation of vating images is halved to save computations. The exposes composing the Gaussian and DoG scale space can then be arranged as in the bare figure:.
Notice that the scale level index s varies in a slightly redundant set..
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 if you want to remove all the inherited entries from the ACL. You can easily change the propagation value.
