The following demonstrates a bidirectional landmark based image warping. The upper left corner shows a source image. The upper right corner contains the target image. Your task is to define a set pairwise corresponding landmarks in both images. Once you are done, press the Warp button. The program will warp the source image onto the target image so that every landmark point defined in the target image will go to the corresponding landmark in the source image. The warped image appears in a bottom left corner. Another warped image is computed by inverting the source and the target images. Using the dropdown lists, you can choose from images of several of our staff members to play with.
