| Abstract(in English) | This paper presents a new method for automatically separating the motion of multiple independently moving objects in a sequence of images based on the notion of illumination subspace. We show that intensities of observed trajectories of image features on a single body lie on a linearly independent frame space with three, or fewer, dimensions. We then argue that it is possible in theory to determine the grouping of the feature points by way of separating the illumination subspaces. As a clue for practical separation, we also introduce the surface interaction matrix which is valid for Lambertian reflectance surface. While several authors have recently presented different algorithms on this task of grouping by factorization-based procedures using the coordinates of image features, we propose to incorporate the above photometric analysis available at given feature points in the conventional schemes of motion segmentation. We show that the performance is stabilized through experiments on real and synthetic image sequences. |
