Abstract: A method for effectively and conveniently processing images includes the steps of: providing an original image having a first set of coordinate points, wherein the points respectively have digital data; defining the original image as a connection of edges approximating the original image, wherein endpoints of the edges are a second set of coordinate points; performing a first operation on the first and second sets of coordinate points to obtain a relation map function corresponding to the first set of coordinate points; performing a second operation on the digital data of the first set of coordinate points associated with the relation map function to process the original image.
