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 applications 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.
