Abstract :
A novel edge-preserving image interpolation algorithm is introduced. It is based on the use of a simple nonlinear filter which reconstructs sharp edges accurately and without the ringing effects which are present in other interpolation techniques. Some simulation results on one- and two-dimensional data are presented, and a possible VLSI implementation is discussed
