... 3D image sharpening by grid warping . ... A method for sharpening of 3D volume images has been developed. The idea of the proposed algorithm is to transform the 3D 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 pixel grid. ... The effectiveness of the proposed method is demonstrated with synthetic volume images and real micro CT images. ... Title = {3D image sharpening by grid warping}, . ...

... Grid warping for image sharpening using one-dimensional approach . Publication type . Conference paper . ... Conference . ... 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. ...
... Deblurred images post-processing by Poisson warping . Publication type . ... Publication date . ... In this work we develop a post-processing algorithm which enhances the results of the existing image deblurring methods. It performs additional 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. ...
