Abstract :
This paper discusses the use of connected operators for robust motion estimation. The proposed strategy involves a motion estimation step, extracting the dominant motion, and a filtering step, relying on connected operators that remove objects that do not follow the dominant motion. These two steps are iterated in order to obtain an accurate motion estimation and a precise definition of the objects following this motion. This strategy can be applied on the entire frame or on individual connected components. As a result, the complete (motion-oriented) segmentation and motion estimation of the frame can be achieved
