Abstract: This paper describes an automatic framework to convert a video clip to a vectorized animation. First the whole video is segmented by an improved Anisotropic Kernel Mean Shift algorithm where the computation of density function has been refined,and 3D segmentations of the video are obtained.Then by contouring tracking,and representation by Bézier curves,the color patches are retrieved.Finally the color patches are smoothed between frames to produce a continuous vectorized animation.By a little editing on this conversion result,non-professional designers can produce complex and nice Flash animations.
