4. What is image morphing? Image morphing deals with the metamorphosis of an image to another image. The metamorphosis generates a sequence of in between images in which an image gradually changes into another image over time.

6. Classification of technology warping based on mesh warping based on line warping based on points

7. Classification of technology (1) based on the mesh of the deformation of the image into a number of blocks, using each block of the deformation of the overall combination of image deformation, the advantage is that the deformation is fast, but the image preprocessing is more cumbersome, and the effectiveness and rationality of image segmentation will directly affect the effect of deformation

8. Classification of technology (2) construct a series of feature lines on the image based on the (feature) line deformation, and use the feature line to carry out pixel migration. This method deforms slowly and unintuitively

9. Classification of technology • (3) the image is regarded as scattered points based on (feature) point deformation, and the spatial mapping of all points is completed through the spatial mapping of some special points and the appropriate radial basis function. This method is intuitive but some radial basis functions are very complex functions such as gaussian functions, so the deformation rate is very slow
