Abstract:
This paper considers human body motion analysis as local changes of orientations in hierarchical skeleton parts over time. Possible approaches by applying multiresolution analysis in form of a second generation wavelet transform directly on quaternion signal are shown. Quaternions in terms of motion analysis are a more efficient representation of rotation than Euler angles. This paper presents that the lifting scheme can be efficiently applied directly to quaternions. Lifting scheme building blocks for the quaternion Haar and linear transformation are presented.
