Feature point tracking for incomplete trajectories with multiview constraint
Kunpeng Wang · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2012
A new algorithm is presented for feature point tracking with multi-view constraint. Dynamic scenes with multiple, independently moving objects are considered in which objects may temporarily disappear, enter and leave the view field. Different from most of existing approaches to feature point tracking, 3D spatial geometry constraint is utilized to make tracking more stable and fit the real 3D motion of objects, linking flags and matching flags is proposed to describe the complex relationship of feature points observed by multiple cameras. Results for synthetic motion sequences are presented.
