 demo_statistics.m is a Mathematica program which allows to
investigate the error of reconstruction for syntetic random data with arbitrary many spherical cameras in space
and arbitrarily many points. An error is added to the syntetic pictures and then the reconstruction done.
It is one of the programs we used to experimentally investigate the stability of the reconstruction.
 simulation3d_vel.m is a Mathematica program which demonstrates
the reconstruction of camera and point particles as particle velocities from pictures. Having the possiblity to
reconstruct moving bodies as well as the cameras is a justification for a relatively general definition of the
structure from motion problem.
