#127: Generalize the definition of the Sobel gradient -------------------------+-------------------------------------------------- Reporter: levill_r | Owner: Olena Team Type: enhancement | Status: new Priority: trivial | Milestone: Component: Milena | Version: 1.0 Keywords: | -------------------------+-------------------------------------------------- For the moment (rev. 1656), the Sobel gradient only works on 2-D images. We could generalize its definition to n-D (regular) images. For instance, a 3-D version is mentioned in http://www.aravind.ca/cs788h_Final_Project/gradient_estimators.htm. -- Ticket URL: <https://trac.lrde.org/olena/ticket/127> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image library.
