Function S-rough Sets and image F-interior hiding

Function one direction S-rough sets (Function one direction singular rough sets) is defined by R -function equivalence class. A function is a curve or a line. Function one direction S-rough sets has curve characteristics and dynamic characteristics. By using function one direction S-rough sets, the concept of image F -interior hiding is presented; the theorem of image F -interior hiding and the recognition criteria of image F -interior hiding are proposed; and the applic-ations of image F -interior hiding are given. Image F -interior hiding is a new application area of function S-rough sets, and function S-rough sets is a new theory and new tools for iconology research.
