ABSTRACT
Morphing" describes the combination of image warping with a cross-dissolve between images. This term is basically derived from "image metamorphosis". It is an image processing technique which is used as an tool of animation for the metamorphosis from one image to another. The idea is to specify a warp that distorts the first image into the second and its inverse will distort the second image into the first. The first image is gradually distorted and is faded out, while the second image starts out totally distorted toward the first and is faded in. Thus, the early images in the sequence are much like the first source image. The middle image of the sequence is the average of the first source image distorted halfway toward the second one and the destinationimage distorted halfway back toward the first one. The middle image is key if it looks good then probably the entire animated sequence will look good. For morph between faces, the middle image often looks strikingly life-like, like a real person, but clearly it is neither the person in the first nor second image. The morph process consists of warping two images so that they have the same "shape", and then cross dissolving the resulting images.
