Algorithm of image metamorphosis based on blending rational interpolation
基于混合有理插值的图像渐变算法*

Aiming at the problems of merely considering metamorphosis between two images, this paper presented a new non-linear method of image metamorphosis among multiple images based on rational interpolation. First, constructed a correspon-ding relationship between pixels having same coordinate among multiple images. And then produced rational interpolation function based on this correspondence. Finally, generated series of morphing images by resampling the rational interpolation function. The experimental results show that this algorithm is better than several other algorithms both in distribution of data and integrality of image texture. This algorithm has the high precision of calculation, strong adaptation and easiness of programming, so it is a more practical algorithm.
