基于Morphing算法的定格场景动画生成方法研究

About the Freeze-frame Scene Animation Generation Method Based on Morphing Algorithm

为生动展现定格场景,提出基于Morphing算法的定格场景动画生成方法。使用Canny算子提取定格场景图像的轮廓线,据此生成能控制定格场景中目标对象的源网格,创建所得定格场景图像源网格与目标网格的匹配关系,获取Morphing序列,得到网格相应的对齐图像。通过透射率估计方法融合对齐定格场景图像,实现定格场景动画生成。实验结果表明:该方法可以提取完整的定格场景图像轮廓线并有较理想的网格配准效果,且在满足人眼视觉舒适度的前提下,生成的定格场景动画能清晰地还原真实场景的特点及结构。

To vividly display the freeze-frame scene with definitive pictures,a freeze-frame scene ani⁃mation generation method based on morphing algorithm is proposed.The contour lines of the freeze-frame im⁃age are extracted by using the Canny operator and the source grid which can control the target objects in the freeze-frame scene,is generated accordingly.The matching relationship between the source grid and the tar⁃get grid of the freeze-frame scene image is created,to obtain the Morphing sequence and get the correspond⁃ing aligned image of the grid.By fusing the aligned freeze-frame scene images through the transmittance esti⁃mation method,the freeze-frame scene animation generation is realized.Experimental results show that this method can extract complete contour lines of the this kind of image with ideal grid registration effect.On the premise of satisfying the human visual comfort,the generated freeze-frame scene animation can clearly re⁃store the characteristics and structure of the real scene.
