Abstract
We present a stylistic walk modeling and synthesis method based on frequency analysis of motion capture data. We observe that two peaks corresponding to the walk cycle fundamental frequency and its first harmonic can easily be found for most walk styles in the Fourier transform. Hence a second order Fourier series efficiently represents most styles, as assessed in the subjective user evaluation procedure, even though it results in a strong filtering of the original signals and hence a strong smoothing of the resulting motion sequences.
