Boundary Stabilized Image Morphing with Asymmetrical Radial Basis Functions

Traditional image morphing algorithm using symmetrical radial basis functions often causes distinct warping on image boundary.An approach of introducing asymmetrical radial basis functions is presented to control asymmetrical range and hence keep the boundary of morphed image stable.Experimental results show that such an approach is effective and the morphed images give good local morphing results with fair smoothness comparable to that produced by symmetrical radial bases,and most importantly,have stable image boundary.
