Multilinear Motion Synthesis


We propose a level-of-detail control method of motion synthesis with a multilinear model. Our method first extracts a small number of principal components of motion samples by analyzing three-mode correlations among joints, time, and samples using tensor decomposition. A new motion is synthesized by interpolating the reduced components, where the prediction accuracy of the resulting motion is controlled by adaptively decreasing the data dimensionality.
