... Laboratory of Mathematical Methods of Image Processing . ... Grid warping for image sharpening using one-dimensional approach . ... A new method for image sharpening via image warping is proposed. The idea of the method is to warp the uniform grid of the image in a way that the pixels around the blurred edge move closer to the edge according to its blurriness. ... Also, since image warping does not change pixel values and only moves pixels, the developed method does not increase the noise level. ...
