Image Restoration Based on Robust Method
Ruihua Liu · 2008
In this paper,we study a class of degraded images with salt pepper noise and stick shape,such as crossing.Combining the advantages of wiping off salt pepper noise by robust method with protecting edge by p(x)-harmonic map,we establish a variational model,and then iterative an evolvement equation by the steepest descent to conduct experiments.From simulation results,our method preferably keeps the edge of original image.
