1. Computer-implemented method for tracking and reshaping a human-shaped figure in a digital video comprising the steps:
- acquiring a body model of the figure from the digital video;
adapting a shape of the body model;
modifying frames of the digital video, based on the adapted body model; and
outputting the digital video,wherein pose and shape parameters of the model are acquired by measuring the misalignment of a silhouette boundary of a re-projected model with a silhouette boundary of the figure, andwherein acquiring pose and shape parameters further comprises minimizing a misalignment between the figure in a video frame and the body model re-projected onto the video frame.

10. A computer-implemented method for tracking and reshaping a human-shaped figure in a digital video, the method comprising:
-
providing an interface for setting shape attributes of a body model; wherein the shape attributes of the body model comprise at least one of height, weight, breast girth, waist girth, hips girth, leg length and muscularity; acquiring a body model of the figure from the digital video; adapting a shape of the body model, wherein the shape of the body model is adapted by mapping shape attributes set via the interface to the shape; modifying frames of the digital video, based on the adapted body model; and outputting the digital video. - View Dependent Claims (14, 15, 16)
