Motion signal processing

TLDR

Techniques from image and signal processing can be successfully applied to designing, modifying, and adapting animated motion. We introduce multiresolution motion filtering, multitarget motion interpolation with dynamic timewarping, waveshaping, and motion displacement mapping. The approach employs these techniques to reuse and adapt existing motion data—joint angles, coordinates, or higher‑level parameters—of articulated figures with many degrees of freedom. Existing motions can be modified and combined interactively at a higher abstraction level, complementing keyframing, motion capture, and procedural animation.

Abstract

Techniques from the image and signal processing domain can be successfully applied to designing, modifying, and adapting animated motion. For this purpose, we introduce multiresolution motion filtering, multitarget motion interpolation with dynamic timewarping, waveshaping and motion displacement mapping. The techniques are well-suited for reuse and adaptation of existing motion data such as joint angles, joint coordinates or higher level motion parameters of articulated figures with many degrees of freedom. Existing motions can be modified and combined interactively and at a higher level of abstraction than conventional systems support. This general approach is thus complementary to keyframing, motion capture, and procedural animation.
