m e t h o d s . I t p e r f o r m s a d d i t io nal edge sharpening using grid
warping. The idea of the proposed algorithm is to transform
the neighborhood of the edge so that the neighboring pixels
move closer to the edge, and then resample the image from the
warped grid to the original uniform grid. The proposed technique
preserves image textures while making the edges sharper. The
effectiveness of the method is shown for basic deblurring methods
on LIVE database images with added blur and noise.
