MovieReshape: Tracking and Reshaping of Humans in Videos

摘要

We present a system for quick and easy manipulation of the bodyrnshape and proportions of a human actor in arbitrary video footage.rnThe approach is based on a morphable model of 3D human shapernand pose that was learned from laser scans of real people. The algorithmrncommences by spatio-temporally fitting the pose and shapernof this model to the actor in either single-view or multi-view videornfootage. Once the model has been fitted, semantically meaningfulrnattributes of body shape, such as height, weight or waist girth, canrnbe interactively modified by the user. The changed proportions ofrnthe virtual human model are then applied to the actor in all videornframes by performing an image-based warping. By this means, werncan now conveniently perform spatio-temporal reshaping of humanrnactors in video footage which we show on a variety of video sequences.
