Image metamorphosis using simple features provides flexible and easy control of visual effect. The feature-based image metamorphosis algorithm proposed by Beier and Neely suffer from two problems; speed and strange effects. This paper presents an optimization technique to recover these problems in a reasonable time. The idea is based on local decomposition of metamorphosis into piecewise approximation and then applying Beier's technique to establishe one-to-one correspondence to recover such effects. The combination of all mapping produces the result of foldover-free as well as dominates the ghost effect. The results show that our implementation is efficient in time complexity, smoothly interpolated metamorphosis images with only a remarkably small number of specified feature points, and the speed of computations makes image metamorphosis animation reliable for interactive machine.
