PT Journal AU Carme Julia Angel Sappa Felipe Lumbreras Joan Serrat Antonio Lopez TI Rank Estimation in 3D Multibody Motion Segmentation SO Electronic Letters PY 2008 BP 279 EP 280 VL 44 IS 4 AB A novel technique for rank estimation in 3D multibody motion segmentation is proposed. It is based on the study of the frequency spectra of moving rigid objects and does not use or assume a prior knowledge of the objects contained in the scene (i.e. number of objects and motion). The significance of rank estimation on multibody motion segmentation results is shown by using two motion segmentation algorithms over both synthetic and real data. ER
