Reconstructing the Human Form
◮ 3-D point data from CMU motion-capture database.
◮ Uniform mixture of frames from walking, jumping,
runnning and dancing motions.
◮ Similarity matrix computed from inter-point squared
distances; can be interpreted as a stiffness matrix of a
physical spring system.
◮ Cond. independence across frames and across features
(sensor coordinates). Meaning each y contains only one
of x, y or z coordinates of 31 sensors of one frame.
◮ ∼7000 frames × |{x, y, z}|
Y ∈ R 21000×31
