Image enhancement using warping technique
Josep Prades-Nebot, P. Mateu-Villarroya, Julio Pons, Rafael Rodríguez García · Electronics Letters · 2003
An image enhancement algorithm based on a warping technique is presented. The warping map is chosen in order to sharpen the edges of the image. In contrast to other algorithms, enhancement is performed without introducing overshoot in sharp edges and without amplifying the noise present in the original image.
