Spatiotemporal dance representation model of samba, parameterized with quarter-beat resolution and variability, within two-beat metric cycles (i.e., dance represented by the spherical distributions of eight metric classes, which correspond to resolution * 2beats): (a) point cloud representation of the dance gesture of the left hand; (b) point cloud after LDA analysis. Note that classes of points are visually and linearly discriminated from each other; (c) representation of point clouds as homogeneous spherical distributions around the mean trajectories of the left hand.
