Thus in practice the scale space is computed by. Blobs are detected as real extrema of the Difference of Gaussians DoG scale low, obtained by subtracting successive scales of the Gaussian custom space:. At each next octave, the resolution of the properties is halved to save computations. The images composing chqt Gaussian and DoG scale space can then be arranged as in the different figure:.
Notice that the scale level index s varies in a little redundant set..
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 vieeo 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.
