Grid-distortion on nonrectangular grids Original Research Article

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 curve sets arranged in a regular rectangular grid were considered. In this work we construct smooth (C1) grid-distortion mappings defined by curves arranged in a nonregular structure, and characterize the most general grids for which our procedure is valid.
