  • Method and apparatus of image morphing by edges mapping and computer accessible storage medium thereof
    Patent number: 7952593
    Abstract: An image morphing method is suitable for generating an intermediate image sequence. First, a control point CP={(pi,qi)}i=1 . . . N is specified and marked in a source image Is({right arrow over (x)}) and a destination image Id({right arrow over (x)}?). Next, an edge gradient parameter (Ise({right arrow over (x)}), Ide({right arrow over (x)}?) is computed according to the source image Is({right arrow over (x)}) and the destination image Id({right arrow over (x)}?). Next, a total objective function E(Df,Db) is computed according to the above-mentioned control point CP and edge gradient parameter (Ise({right arrow over (x)}), Ide({right arrow over (x)}?)). The above-mentioned intermediate image sequence is generated by using the total objective function E(Df,Db). The present invention utilizes the edge gradients of the source image Is({right arrow over (x)}) and the destination image Id({right arrow over (x)}?) to enhance the constraint of image morphing. Thus, the image morphing effect is promoted.
