Grid-Distortion on Non-Rectangular Grids

Grid-distortion is an image warping technique which is driven by the mapping between equivalent families of curves, arranged in a grid structure. Until recently only curves sets arranged in a regular rectangular grid were considered. In the present work we construct a smooth (C 1) grid-distortion mappings deened by curves arranged in a non-regular structure , and fully characterize the most general grids for which our procedure is valid.
