Abstract

We propose a method to generate animations using video-based mesh sequences of elementary movements of a shape. New motions that satisfy high-level user-specified constraints are built by recombining and interpolating the frames in the observed mesh sequences. The interest of video based meshes is to provide real full shape information and to enable therefore realistic shape animations. A resulting issue lies, however, in the difficulty to combine and interpolate human poses without a parametric pose model, as with skeleton based animations. To address this issue, our method brings two innovations that contribute at different levels: Locally between two motion sequences, we introduce a new approach to generate realistic transitions using dynamic time warping; More globally, over a set of motion sequences, we propose the essential graph as an efficient structure to encode the most realistic transitions between all pairs of input shape poses. Graph search in the essential graph allows then to generate realistic motions that are optimal with respect to various user-defined constraints. We present both quantitative and qualitative results on various 3D video datasets. They show that our approach compares favourably with previous strategies in this field that use the motion graph.
