Many important properties of stack filters (idempotency, co-idempotency, order relations) can be tested in polynomial time if the DNF and/or CNF of b are known.  ...  Stack filters are nonlinear filters used for image processing (examples: median filters, order statistics).  ...  When is a min-max operator then the topical operator I − is never a min-max operator, but again there is a polynomial algorithm to decide its idempotency (Section 4.2). Theorem 5.  ...

Two procedures to compute the output distribution phi_S of certain stack filters S (so called erosion-dilation cascades) are given.  ...  One rests on the disjunctive normal form of S and also yields the rank selection probabilities. The other is based on inclusion-exclusion and e.g. yields phi_S for some important LULU-operators S.  ...  This framework is based on concepts like idempotency, co-idempotency, trend preservation, total variation preservation, consistent decomposition.  ...

In this work, we considered the definition of min, max, direct and subtractive filter rules for the computation of attribute filters over the tree of shapes representation.  ...  Among those, connected operators (e.g., attribute filters) have proven their effectiveness in processing very high resolution images.  ...  This idea has been formalized as the so-called shape filters [26] , and the operators which are anti-extensive and idempotent are not necessarily increasing.  ...

We introduce a theory of stratifications of noncommutative stacks (i.e. presentable stable ∞-categories), and we prove a reconstruction theorem that expresses them in terms of their strata and gluing data  ...  We also provide a suite of fundamental operations for constructing new stratifications from old ones: restriction, pullback, quotient, pushforward, and refinement.  ...  The main results that we use are the definition and basic properties of lax functors, the construction of left-laxification, and the Grothendieck construction for (∞, 2)-categories (which are unconditionally  ...
