| Description | in Proceedings of 40th Annual Allerton Conference on Communication, Control, and Computing We study the problem of estimating the motion of independently moving objects observed by a moving perspective camera. Given a set of image points and their optical flow in multiple frames, we show how to estimate the number of independent motions, the segmentation of the image points, the motion of the camera and that of each object. We do so by combining the so-called subspace constraints with the Costeira and Kanade algorithm for orthographic cameras [3]. We evaluate the proposed algorithm on synthetic and real image sequences. |
