该程序基于2D特征点的移动轨迹,估计独立运动的对象数目.-Given 2D trajectories of feature points moving in the

　　image frame, this program estimates the number of

　　independent motions using model selection by the

　　geometric AIC (default) or the geometric MDL (option) based on

　　the subspace separation method (default) or the affine space

　　separation method (option). The estimated number of motions is

　　returned to the standard output.
