Bilateral Motion Spectra - Analysis and Representation of Human Movement

Anthony Schultz

2014

Abstract

The body’s bilateral symmetry allows for various kinds of human motion patterns. Our paper presents a method for analyzing and representing motion capture time series that effectively identifies spatial and temporal patterns. We develop a factored representation of joint angle data based on quaternions and a metric pair for comparing different physical states of articulation. This metric pair is used to generate a metric space pair over the set of time series states. The result is represented as a 2-dimensional color image termed a bilateral motion spectrum. Several spectral motifs are presented and characterized.
