Scattered data points based image warping use a coordinate transformation that maps a set of points locations in a source space to another set of points in the warped destination space. In this paper, we propose a new spatial image warping algorithm which uses elastic body spline to generate a warp function that interpolates scattered data points. The spline is based on a physical model for the deformation elastic body. The spline maps can be expressed as the linear combination of an affine transformation and Navier interpolation spline. The proposal algorithm generates a smooth warp that reflects the feature points and prevents the warped image from folding back upon itself. Also, we compare our proposal algorithm with thin plate spline algorithm.
