Multiframe-based identification of mobile components of a scene with a moving camera
Édouard François, Patrick Bouthémy · 2002
The authors deal with analysis of the dynamic content of a scene from an image sequence whatever the camera situation is (static or mobile). This problem involves a motion-based segmentation step. A method which ensures stable motion-based partitions owing to a statistical regularization approach is presented. It does not require the explicit estimation of optic flow fields and manages to link those partitions in time. The identification of the kinematical components of the scene relies on an intermediate layer accomplishing a generic qualitative motion labeling. This is achieved considering jointly several successive images. No 3-D measurements are required. Results obtained on several real image sequences corresponding to complex outdoor situations are reported.>
