%X Image warping is one of the popular approaches in computer animation and using this technology we can change a given image into its warping image by some user defined features. Based on the radial basis interpolation function algorithm, an improved image warping method is proposed, which can transform the original optimize prob- lem to nonsingular linear problem by adding one-order term and affine differentiable condition. In the same time, this linear system may get steady unique solution by choosing suitable kernel function. Furthermore, the method how to set up the radial basis function in the target image is given too, it provides necessary support to obtain slippery warp- ing image, which uses the backward re-sampling technology. Experimental results show that improved algorithm can implement smooth and gradual image warping under multi-anchor points' accurate interpolation.
