摘要

Motion segmentation is one of the key techniques in the context of motion analysis and generation. The basic idea is to split motion capture data into continuous segments that can be used to generate new motion sequences. For most applications, this segmentation is done manually leading to inaccurate and inconsistent results. This makes it difficult to conceive general methods for subsequent reassembly. This paper proposes an automatic segmentation of motion capture data that results in deterministic segmentation points. The method can be considered as an advanced zero crossing segmentation technique. As zero crossing performs poorly on weak motion, a threshold is defined detecting phases of week motion. We distinguish two states: One for the resting phase and one for phases of movement. Splitting this second phase again, the presented approach leads to a symbolic level allowing later steps to be carried out without the need of considering spatio-temporal dependencies.
