Scientists of the Max Planck Institute for Informatics in Saarbrücken present a system for quick and easy manipulation of the body shape and proportions of a human actor in arbitrary video footage. The approach is based on a morphable model of 3D human shape and pose. Once the model has been fitted to the actor, semantically meaningful attributes of body shape, such as height, weight or waist girth, can be interactively modified by the user. The changed proportions of the virtual human model are then applied to the actor in all video frames by performing an image-based warping. The video sequences show how the scientists can conveniently perform spatio-temporal reshaping of human actors.
