Embodiment Construction
[0021] Combine below figure 1 , figure 2 and image 3 The present invention is further described.
[0022] The method of the invention transforms the deformation problem of the image into the deformation problem of the corresponding grid M. This method first takes an image I(x) as input, and constructs a quadrilateral mesh M corresponding to the deformed region D with a pixel interval d. For the convenience of processing, the grid is composed of several squares with side length d. The smaller d is selected, the closer M is to the shape of D, but it also increases the calculation amount accordingly. Since the method of the present invention is oriented to the field of animation production, the details of the shape of D are not critical, so a larger value can be selected for d, as long as it properly reflects the required details. The meshing process regards D as an image map on the mesh M, and records the corresponding mapping coordinates of each mesh vertex. Since the v...
