Abstract
Images of scenes with moving objects, taken from a moving camera, have several motion components. The dominant image motion is usually generated by the camera motion which affects the stationary background. Moving objects contribute to other motion components. An iterative method is described for segmenting image sequences into independently moving regions while computing the motion parameters of each region. In each iteration, image points are classified to regions based on their consistency with the different motion estimates, and motion estimates are then updated using the obtained regions. The motion estimates and the segmentation improve with every iteration, and the iteration stops when a stable segmentation is obtained. Accurate motion parameters are recovered for each segment. The proposed process is performed directly on grcydevel images, and does not require detection of special feature points and the computation of point correspondence. It is also faster and more robust than optical flow based segmentation methods.
