Image interpolation algorithm based on edge degree
Fan-ting KONG, Jun-hua LIU · Journal of Computer Applications · 2012
In order to eliminate the phenomenon of contour jaggies in conventional image interpolation schemes,an edge-degree-based image interpolation method was proposed.Under the smooth contours assumption,the method considered the smoothly varying characteristics of nature image contours,and utilized the information of edge degree to suppress contour jaggies.Simulation results show that the proposed method produces fewer jaggies,and it doesn't introduce other obvious artifacts.Furthermore,the method still preserves the simplicity and efficiency of conventional image interpolation methods,and is easy for implementation and application.
